Question

Plugin y=-5 into either equation and solve for x
-6x-8y=-20 or x+y=5

Answer 1

Explanation:

Substitute y = 5 into the equation:

`- 6x - 8( - 5) = - 20`

Multiply:

`- 6x + 40 = - 20`

Subtract 40 from each side:

`- 6x = - 60`

Divide each side by -6:

`x = 10`

Substitute y = -5 into the equation:

`x - 5= 5`

Add 5 to both sides of the equation:

`x = 10`

x will equal 10.
