rearranging that equation you'll have the value of y in terms of x

y = -2x + 6 -----equation 3

you substitute that value attained to the second equation.. say you have the second equation as 3x + y = 10 ---equation 2

substituting equation 3 to equation 2 you'll hvae

3x + y = 10

3x -2x + 6 = 10

x = 10 - 6

x = 4

substituting the value of x in equation 3 you'll have

y = -2x + 6

y = -2(4) + 6

y = -8 + 6

y = -2
