Please help me its about Solving by substitution
Vera_Pavlovna [14]

Answer:

x=-2 y=3

Step-by-step explanation:

The substitution is basically given to you. Exchange x from the second equation with y-5

Once that is done and you combine the parentheses you get:

2y-10+y=-1

Add 10 on both sides of the equal sign

You get:

3y=9

Divide both sides by 3

You get:

y=3

To check your work you can substitute y in the second equation with 3 and solve it that way to get x=-2 (x equals negative two)
