Simple Equations

w + 12 = 20

• w = 32
• w = -32
• w = 8
• w = -8

3x = 36

• x = 18
• x = 12
• x = 6
• x = 33

^x/₄ = 2

• x = 8
• x = 2
• x = 0.5
• x = 6

x - 8 = -5 

• x = 13
• x = -13
• x = 3
• x = -3

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.

Form the equation for the following statement :

'one third of y is 25'

• y + 3 = 25

• y ⁄3 = 25

• 3y = 25

• y - 3 = 25
