​ One goal of this course will be to review and enhance your algebra skills. Solve for x in each equation below, show and justify all steps leading to your solution, and check your answer. Homework Help ✎

a.

34x − 80 = 10x − 8

34x − 80 = 10x − 8
−10x = −10x Subtract 10x from both sides
24x − 80 = −8

24x − 80 = −8
+80 = +80 Add 80 to both sides
24x = 72

24x = 72 (Divide both sides by 24.)

b.

4x − 5 = 4x + 10

No solution.

c.

3(x − 5) + 2(3x + 1) = 41

3x − 15 + 6x + 2 = 41

d.

−2(x + 4) + 6 = −3

Remember to combine only like terms.
