Question

Y=-1,X+2y=-6 solve by substitution show all work

Answer 1

x = -4, y = -1

Explanation:

Simple, just plug the Y in

(Pemdas)

x+2(-1) = -6

x-2 = -6

x = -4

-4+2y = -6

2y = -2

y = -1

Answer 2

`x=-4`

Explanation:

`x+2y=-6`

`y=-1`

_________

`x+2\left(-1\right)=-6`

`x-2* \:1=-6`

Multiply: 2*1= 2

`x-2=-6`

Add 2 to both sides:

`x-2+2=-6+2`

`x=-4`
