Solving Linear Equations

What is your first step to solve for x in the following equation:

5 + x = -12

• Add 12 to both sides

• Subtract 12 from both sides

• Add 5 to both sides

• Subtract 5 from both sides

Solve for x:

5 + x = -12

• 17

• -17

• 7

• -7

What is the first step to solve for x?

5x + 3 = 18

• Divide both sides by 5

• Subtract 18 from both sides

• Subtract 3 from both sides

• Subtract 5x from both sides

Solve for x:

5x + 3 = 18

• 15

• 21/5

• 3

What is the first step to solve for x in the following equation:

6x - (-5x + 1) = 15x - 2x - 5 + 4

• Combine like terms

• Distribute the invisible negative 1 outside the parenthesis

• Subtract 15x from both sides

• Add 2x to both sides

What is the next step to solve this equation?

6x + 5x - 1 = 15x - 2x - 5 + 4

• Combine like terms

• Subtract 15x from both sides

• Subtract 6x from both sides

• Add 5 to both sides

What is the next step to solve this equation?

11x - 1 = 13x -1

• Subtract 11x from both sides

• Add 1 to both sides

• Subtract 13x from both sides

• Divide both sides by 13

What is the next step to solve this equation:

- 1 = 2x -1

• Divide by 2

• Add 1 to both sides

• Subtract 2x from both sides

• Combine like terms
