Solving Simple Equations
For each question, find a value of x which
satisfies the equation

• 3x 12
• 3 x 7
• x 9 11
• 7x 35
• x 12 27
• x 6 29
• 4x 88
• 5x 65

• x 4
• x 4
• x 20
• x 5
• x 15
• x 35
• x 22
• x 13

A Trickier Problem
3x 7 11
First find 3x Adding 7 to both sides gives us
3x 11 7
So if we divide by 3 we get
x 6
