Best ResponseYou've already chosen the best response.0For example x=12. 3(x)+2=y 3(12)+2=y < 36+2=y  38=y   See how I substituted x as 12 to solve the example equation?

Best ResponseYou've already chosen the best response.0Example: x+2=y You know that x is 1 but you need to find out y. So you put \(\color{red}{x~as~1}\) in the equation. \(\color{red}{(1)}\)+2=y. 1+2=3 so y=3. Get it?

Best ResponseYou've already chosen the best response.11not just 16 m^2 16 should be together \[\huge\rm \frac{ }{m^2 16 }\] so m^2 and 16= common denominator

Best ResponseYou've already chosen the best response.1now bec denominator of both fraction are same as common denominator so just carry down the value of numerator \[\huge\rm \frac{ 4m17+3m11 }{ m^2 16 }\] now combine like terms 4m17+3m 11= what ?
