Answer:

(-2,-1)

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
