Alg: Review Chapter 1 - Equations and Inequalities

Evaluate the following if x = 3 and y = –1

x + y²(2 + x)

Evaluate the following if w = 2.5

2 | 3w – 8 | + w

Solve for k

2k – 3m = 16

• k = 16 + 3m

Solve the equation

6b – 5 = 3(b + 2)

Solve the equation

–3(a – 3) + 2(3a – 2) = 14

Solve the equation

| 2x + 5 | – 7 = 4

For multiple answers, separate with a comma

Solve the equation

| b + 5 | = 2b – 9

For multiple answers, separate with a comma
