First, you rearrange the equation, to get 3x=6-2y.
Then, you would divide all of the terms by 3, in order to get the value of x
Step-by-step explanation: 3x+2y=6, 2y=6-3x, we want y by itself, so divide by 2 from both sides, y=3-1.5x, then we plug it into the equation,3x+2(3-1.5)=6, then solve. 3x+6-3x=6, 3x-3x=0,so 6=6, y could be any possible answer
b, i believe, but not sure.
