Best ResponseYou've already chosen the best response.0Okay so how would I do that?

Best ResponseYou've already chosen the best response.1\[J=M+7, (J+5)+(M+5)=53\]

Best ResponseYou've already chosen the best response.1Because Juwan is seven years older that Monica, hence J=M+7 and the sum of their ages will be 53 in 5 years (5 plus their current age). Now, you may use the substitution method to solve for their age.

Best ResponseYou've already chosen the best response.0Okay what is the substitution method?

Best ResponseYou've already chosen the best response.0j+5+m+5=53 if j=m+7 then the substitution method is to put m+7 in j's place so m+7+5+m+5=53 2m+17=53 17 17 2m=36 m=18 right now m=18 and j=25

Best ResponseYou've already chosen the best response.0The substitution method basically means that if two things are equal, you can swap them. For example, if the equation is b=a+2 and you knew that b=3, you could change the problem to 3=a+2 in order to solve for a=1. Does that make sense?
