1-23.

Solve each linear equation. Check your solutions.

Add 3 to both sides.

−2*x*− 3 = 3

+3 +3

−2*x*= 6Divide both sides by −2

*x*= −3

Add 3 to both sides.

7 + 2*x*= 4*x*− 3

+3 +3

10 + 2*x*= 4*x*Subtract 2

*x*from both sides.

10 + 2*x*= 4*x*

-2x -2x

10 = 2*x*Divide both sides by 2.

*x*= 5
