the last one! im not sure if this one is right though.

Answer 3

wrong
let me explain it

suppose there are two equations
A : x= 2y+3
B : x= 3y +9
now you have to substitute one equation in to the other
just put the value of x in equation A in Equation B at the place of x
in equation A the value of x is 2y+3
now guess what will be the answer
