Solving Multistep Equations with Variables on Both Sides

Solve for f:
f - 4 = 6f + 26

• f = -5
• f = 5
• f = 6
• f = -6

Solve for x:
5x - 14 = 8x + 4

• x = 6
• x = -6
• x = -18/13
• x = 10/3

Solve the equation:
7x - 4 = 3 + 8x

• x = 7
• x = -7
• x = 2/7
• x = 11

14p - 8 = 22 + 20p

• -5

• 5

• 30

• -30

What is the first step to solve this equation:

-11 - 3x = 44 - 2x

• Add 3 to both sides

• Get the variable on one side

• Add 11 to both sides

• Add 2 on both sides.

2x = x + 3

• 6
• 3
• 2
• x

7x = 3x + 24

• 6
• 10
• 14
• 4

The goal of solving a one, two, or multi-step equations is to:

• Find the constant

• Find the coefficient

• Find the value of the variable

• Be confused
