Solve 1-step and 2-step Equations

How should you show your work to isolate the variable and solve the equation:
x - 62 = 123

• Add 62 to each side. 
• Subtract 62 from each side.
• Multiply each side by 62.
• Add 123 to each side.

Solve:
x÷3=12

• 15
• 9
• 36
• 4

Solve: 
5x = -20

• -4
• -25
• 4
• 25

Solve:
w + (-7) = -10

• 3
• -3
• -17
• 17

Write the equation "4 more than x is 7" and solve. 

• x+4=7
  x = 11
• x+4=7
  x = 3
• x-4=7
  x = 11
• x-4=7
  x=3

Solve:  a/3  - 1 = 4

• a = -15
• a = 15
• a = 9
• a = -9

Solve:  8b + 12 = 52

• b = 8
• b = -8
• b = 5
• b = -5

  Solve:  3 = 5x - 12

• 2 = x
• 4 = x
• 3 = x
• -1 = x

Solve for x:
-30 - 5x = 120

• x = 18
• x = -18
• x = 30
• x = -30

12 = 4 - 4x

• 10
• 8
• 4
• 2
