Solving One- Step Equation

Solve the following equation
X + 8 = 15

• 23
• -7
• 7
• -23

Solve the following equation 
8 = m - 12

• 4
• 0.5
• 5.0
• 20

Solve the equation:
x - 3 = -12

• x = 9 
• x = -15
• x = -9
• x = 15

19  + a  =  -50

• a = -950
• a =  -69
• a = -31
• a = -50/19

Solve the following equation

x + 8 = 15

• x = 23

• x = 22

• x = 7

• x = 6

Solve the equation: 
x + 7 = 12

• x = 5
• x = 19
• x = -5
• x = 84

What is the correct step to solve for the variable?
15 = m - 5

• add 15 to both sides
• add 5 to both sides
• subtract 15 from both sides
• subtract 5 from both sides
