okay how are you doing today I'm good how are you I'm fine how are the day at school I enjoy okay so what are we doing today oh we were going through two-step equations today in a math lesson so I was just wondering if you can explain me the concepts because I was a bit confused in the class okay great so what we'll do is we'll first do the concept on the two-step equation learn about that and then do sit on that is that okay sure great okay I'll just share with you or some files which will help us to get through the concept okay so you can see the screen in front of you yeah I can see that okay so basically try to understand what a two-step equation is an equation in the form ax plus B equals to C can be termed as a two-step equation okay for example 2x plus 5 equals 211 this is a two-step equation so we learn the steps involved and see how we can solve our two-step equation okay so you can see the screen now steps involved yeah I can see this okay the first step says identify what operations are on the variable side what exactly minus 5 equals 211 say this is my equation that is given to me now can you identify these operations what are there on the variable side so I have 2x minus 5 is equal to we have minus sign right left hand side correct and this is subtraction right we have multiplication so basically we have two operations subtraction and multiplication now the next step says undo the operation by using the call that you have to make this quantity 0 now we will undo this operation by using the opposite operation so the opposite traction is addition so I add 5 here equals 211 now we look at the third step whatever you do to one to the other side of the equation to keep it balanced that means I add 5 to the site as well okay we have added five to the left side and to the right side as well now we simplify this the negative five and the positive five becomes zero so we can cancel that so what 2x equals to 16 now right now step four is we go back to step one and repeat the steps now again we identified the operation as we mentioned above it was multiplication now also to undo this we will divide by 2 on both side all right okay so 2x divided by 2 is simply 1x or X how about 16 divided by 2 it's 8 right so x equals to 8 is a solution of this particular two-step equations right all right shall you try one example now you can tell me the directions like you try ok let's take an example 9x minus 1 equals 280 so what is the first have to identify the operation on the variable side that is on the left side okay so the one operation I can say is the multiplication and the other operation I can see on the left hand side is minus 1 so we have subtraction over here correct zero so for that we add one to both sides right right so whatever you are doing on the left side you have to do on the right side also I can simplify this minus 1 will be 0 so 9 X is equal to 81 perfect and all were going to do and then they're going to undo the operations again so we have 9 multiplied by X so we are going to divide it by 9 again left inside and again on the right hand side divided so we would get X is equal to as we divide 81 by 9 we would get 9 mm-hmm so X will be created 9 it's very good for this is the answer for the given equation that we started I hope you have understood the concept now yeah I'm very much playing with the concept now you have done very well and now that you know the concept in method you can try doing some homework problems also on your own right absolute thank you so much thank you so much
