Question

Solve the following system of equations graphically on the set of axes below.

y= 2x-2
y= -x+7

Answer 1

x=y + 2

2

y=2(x - 1)

Explanation:

y=2 x -2

swap sides so that all variable terms are on the left hand side

2x - 2 =y

add 2 to both sides

2x = + 2

Divide both sides by 2.

2 x = y + 2

2. 2

Dividing by 2 undoes the multiplication by 2.

x = y + 2

2

Divide y +2 by 2.

x = y + 1
