Test #3

What would be the best first step to solving the equation?
-3=x+5

• add 3 to both sides
• subtract 5 from both sides
• add 5 to both sides
• subtract -5 from both sides

What would be the best first step to solving the equation?
f+6=-6

• multiply both sides by 6
• divide both sides by 6
• add 6 to both sides
• subtract 6  from both sides

Solve the equation: 
x + 7 = 12

• x = 5
• x = 19
• x = -5
• x = 84

Solve the equation:
x - 4 = 6

• x = 10
• x = -10
• x = 2
• x = -2

r + 20 = 27

• r = 7
• r = 47
• r = 13
• r = 20

S + 4 = 24

• S = 28

• S = 6

• S = 18

• S = 20

x - 12 = 2

• 24

• 10

• 20

• 14
