5(2x -1) = -5+ 10x

• x = 5
• x = 0
• all real numbers
• no solution

Solve for the variable.

22+2a=37+6+a

• a = 21

• a = 5

• a = -5

• a = -16

What is the first step to solve this equation?

3x + 6 = 10 + 3x + 4x 

• Add 4x to both sides of the equation

• Combine like terms 3x and 4x on the same side of the equation

• Add 3x and 6 to get 9x

• Add 6 and 10 to get 16

3(x - 3) ≤ 2(x + 2)

• x ≤ -5
• x ≥ 5
• x ≥ 13
• x ≤ 13

-8x < 48

• x < -6
• x > -6
• x < 6
• x > 6
