Question:

Y= −2x + 8 y = x − 1 explain how you will solve the pair of equations by substitution. show all the steps and write the solution in (x, y) form.

Answers

Hello!

Since y equals both equations they equal each other

-2x + 8 = x - 1

Add 2x to both sides

8 = 3x - 1

Add 1 to both sides

9 = 3x

Divide both sides by 3

3 = x

The answer is 3
