Ch 1 and 2 Review - Solving Equations and Inequalities

What is the first step in solving this equation:
5x + 7 = 12

• Divide by 5

• Subtract 5

• Multiply by 7

• Subtract 7

What is the second step to solve this equation:
11 - 3x = 44

• Add 3 to both sides

• Subtract 11 from both sides

• Add 11 to both sides

• Divide -3 on both sides.

Solve:
2(2x + 3) = -6(x + 9)

• 1.2

• 6

• -6

• 7.5

Describe the solution set:
2(x + 5) = 2x + 5

• one solution

• no solution

• infinitely many solutions

• two solutions
