NEED HELP WILL GIVE BRAINLIEST Consider the following pair of equations:

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.​

x = 3

y = 2

Step-by-step explanation:

y = -2x + 8

y = x - 1

since they both are equal to y, then:

-2x + 8 = x - 1

add 2x to each side of the equation:

-2x + 2x + 8 = x - 1 + 2x

8 = 3x - 1

add 1 to each side:

8 + 1 = 3x -1 + 1

9 = 3x

divide both sides by 3:

9/3 =3x/3

x = 3

substitute for x:

y = 3 - 1 = 2
