Solving One-Step Equations & Spiral Review

The goal when solving an equation is to...

• check the solution

• isolate the variable

• combine like terms

• guess and check

What is the inverse operation needed to solve for p in the equation: 765 = p - 254

• addition

• subtraction

• multiplication

• division

What is the inverse operation needed to solve for b in the equation 80b = 400

• addition

• subtraction

• multiplication

• division

Find the solution in the equation: x - 62 = 123

• 61

• 185

• 186

• 7626

Which equation has x = 5 as the solution?

• x + 15 = 10

• 2x = 5

• 2x = 10

Solve the equation 10 = x - 5.5

• x = 4.5

• x = 5. 95

• x = 5.15

• x = 15.5

How should you show your work to isolate the variable k?

• Divide both sides by 11

• Subtract both sides by 11

• Multiply both sides by 11

• Add 11 both sides

Solve for x:

• x = 10

• x = 20

• x = 7

• x = 3

Which equation has w = 8 as the solution?

• 16 - w = 9

• 16w = 240

• 8w = 64

• 4 + w = 10

Simplify by combining like terms: 7v + 2 + 12 + 2v

• 23

• 23v

• 9 + 14v

• 9v + 14
