please help!? <3
If you were to use the substitution method to solve the following system, choose the new equation after the expression equivalent to x from the first equation is substituted into the second equation.
x + y = 2
3x + 2y = 9
choices:
3(y + 2) + 2y = 9
3(–y + 2) + 2y = 9
3x + 2(y + 2) = 9
3x + 2(–y + 2) = 9
I think it might be C...but I'n most likley wrong.

3(2y)+2y = 9 x + y = 2 x = 2  y 3(2y) + 2y = 9

let x=(2y) 3x + 2y = 9 .............eqn 2 put d value of x in eqn 2 3(2y) + 2y=9 63y+2y=9 6y=9 y=3

so avin y as 3 in eqn 2 3x+2(3)=9 3x6=9 3x=15 x=5
