Two Step Equations

To solve an equation, the goal is to __________ the variable on one side.

• Evaluate
• Leviate
• Isolate
• Reciprocate

What are inverse operations?

• Absolute values
• Opposite operations used in isolating a variable
• Operations used for only inequalities
• Unknown quantity represented by a letter or symbol

A letter or symbol that represents an unknown value is called ______________.

• Variable
• Radicand
• Coefficient
• Constant

A value that when substituted for the variable will make an equation true is a ____________.

• Term
• Constant
• Evaluation
• Solution

The steps in solving 5b - 6 = 24 are: 

• Add 6 to both sides and divide both sides by 5
• Add 6 to both sides and multiply both sides by 5
• Subtract 6 from both sides then multiply both sides by 5
• Subtract 6 from both sides then divide both sides by 5

• r=10

• r=3

• r=7

• r=-6

Identify the steps to solve for b.

• Add 6 to both sides and divide both sides by 5

• Add 6 to both sides and multiply both sides by 5

• Subtract 6 from both sides then multiply both sides by 5

• Subtract 6 from both sides then divide both sides by 5

Solve for x.

• x = 2

• x = -2

• x = -10

• x = 4

20 = 2 - a

• a= 18
• a= -18
• a= -10
• a= 12

Solve for a.

• a= -2

• a= -6

• a= 3

• a= 15
