solving two step equations

33 = 4a - 7

• a=-10
• a=10
• a=4.5

6 - 3a = 21

• a= 9
• a= -9
• a= -5
• a= 5

3 + (¹∕₄)a = 31

• a= 28
• a= 112
• a= 7
• a= 67

7 + ^a⁄₃ = 5

• a= -2
• a= -6
• a= 3
• a= 15

-5 - 6a = -59

• a= 11
• a= -6
• a= 9
• a= 2

What is the first 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  $\frac{x}{5}+2\ =\ 6$  

• t = 20

• t = -20

• t = -40

• t = 40

What was done to solve the equation?

(Line 1) 5x - 8 = 32

(Line 2) 5x = 40

(Line 3) x = 8

• add 8 to both sides, then divide both sides by 5

• add 8 to both sides, then divide both sides by 40

• subtract 8 from both sides, then divide both sides by 5

• subtract 8 from both sides, then multiply both sides by 5

What is the first step to solve for x.  $-9\ +\ 3x\ =\ 10$  

• Subtract 9 from both sides of the equation.

• Add 9 to both sides of the equation.  

• Subtract 3 from both sides of the equation.

• Add 10 to both sides of the equation.
