Solve a system equation

y=-2x-5

y=2x+3

(-2,-1)

Step-by-step explanation:

y=-2x-5

y=2x+3

Since both equations are equal to y, we can set them equal to each other

-2x-5=2x+3

Add 2x to each side

-2x+2x-5=2x+2x+3

-5 = 4x+3

Subtract 3 from each side

-5-3 = 4x+3-3

-8 = 4x

Divide by 4

-8/4 = 4x/4

-2 = x

Now we can find y

y = 2x+3

y = 2 (-2) + 3

y = -1
