Question

Y=-2x+4y
Whats the missing value in the solution to the equation.
(__,-2)

Answer 1

x = - 3

Explanation:

Substitute y = - 2 into the equation and solve for x

- 2 = - 2x + 4(- 2), that is

- 2 = - 2x - 8 ( add 8 to both sides )

6 = - 2x ( divide both sides by - 2 )

- 3 = x

The solution is (- 3, - 2 )

Answer 2

(3,-2)

Explanation:

y=-2x+4y

-2 = 2x + 4(-2)

-2 = 2x -8

-2+8 = 2x

2x = 6

x = 6/2

x = 3

hope it helps!
