Solve each linear equation. Check your solutions. Homework Help ✎

−2

*x*− 3 = 3Add 3 to both sides.

−2x − 3 = 3

+3 +3

−2x = 6Divide both sides by −2

x = −3

7 +

*x*=*x*− 3Add 3 to both sides.

7 + 2x = 4x − 3

+3 +3

10 + 2x = 4xSubtract 2x from both sides.

10 + 2x = 4x

−2x −2x

10 = 2xDivide both sides by 2.

6

*x*− 10 = −8 + 3*x*Refer to part (b).
