Is (6, -4) a solution for the following system of equations? y=8-2x and x+3y=12

Answer 1

(6, -4) does not fit with these two equations

Explanation:

y = 8 - 2x

x + 3y = 12

fit (6, -4) into the equations

-4 = 8 - 2(6)

8 - 2(6) = 8 - 12 = -4

works for this one

6 + 3(-4) = 12

6 + 3(-4) = 6 - 12 = -6

doesnt work for this one
