A-85.

Solve the equations below and check your solutions. Homework Help ✎

−3 + 2

*x*= −*x*+ 65 − 3

*x*=*x*+ 1−2

*x*= 4*x*+ 94

*x*+ 3 =*x*

Add 3 to both sides.

−3 + 2*x* = −*x* + 6

+3 +3

2*x* = −*x* + 9

Add *x* to both sides.

2*x* = −*x* + 9

+*x* +*x*

3*x* = 9

Divide both sides by 3.

*x* = 3

Substitute 3 back into the original equation.

− 3 + 2(3) = −(3) + 6

−3 + 6 = −3 + 6

−3 = −3

It works!

Refer to part (a).

*x* = 1

*x* = −1.5

Use the same method as parts (a), (b), and (c). Make sure to check your answer as shown in part (a).
