Question

A system of equation is shown: 2x = -y + 6 -4x + 3y =8 what is the solution tonthis system of equations? (-1, -4) (1, 4) (4, 4) (-4, -1)

Answer 1

(1 , 4)

Explanation:

2x = -y + 6

-4x + 3y = 8

2x = -y + 6

2x - 6 = -y

-2x + 6 = y

-4x + 3y = 8

-4x + 3(-2x + 6) = 8

-4x - 6x + 18 = 8

-10x + 18 = 8

-10x = -10

x = 1

-2x + 6 = y

-2(1) + 6 = y

-2 + 6 = y

4 = y
