Question

-2x+3y=14
x+2y=7

Answer 1

-2x+3y=14
x+2y=7
I'm guessing you're trying to solve for x and? (:

-2x+3y=14
x+2y=7 → x = -2y + 7 ( I got x alone by subtracting -2y )

Plug x= -2y + 7 to the first equation
-2( -2y +7 ) + 3y = 14 • solve :)
4y - 14 + 3y = 14 • combine the like terms
7y -14 = 14 •add 14 to both sides
7y = 28 •divide
y = 4

Since you now have your y, plug it into x= -2y + 7
x = -2(4) + 7
x = -8 +7
x = -1
