One Step Equations

Solve the equation:
x - 4 = 6

• x = 10
• x = -10
• x = 2
• x = -2

x - 12 = 2

• 24

• 10

• 20

• 14

r + 20 = 27

• r = 7
• r = 47
• r = 13
• r = 20

S + 4 = 24

• S = 28

• S = 6

• S = 18

• S = 20

What would be the best first step to solving the equation?
-18=m+12

• add 18 to both sides
• subtract 18 from both sides
• add 12 to both sides
• subtract 12 from both sides

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

5 less than a number is 15.

• x - 5 = 15
• 5 - x = 15
• 15 - x = 5

Twice a number is 24.

• 2n = 24
• 2/n = 24
• 2 + n = 24
• 2 - n = 24

Solve the following equation
X + 8 = 15

• 23
• -7
• 7
• -23
