SOLVING 2-STEP EQUATIONS

What is the first step in solving this equation:

5x + 7 = 12 Hint: Eliminate the lonely term (constant) 7 first.

• Divide by 5

• Subtract 5

• Multiply by 7

• Subtract 7

Solve:

3(x - 2) = 18. You should know that this is the same as 3x - 6 = 18.

• 6.7

• 4

• 8

• -4

k/5=4 Hint. What is the opposite of "dividing by 5" ?

• 1.25

• 9

• 1

• 20

The variable, k, is being divided by 11. How should you show your work to isolate the variable?

• Divide both sides by 11
• Multiply both sides by 11.
• Add 11 to both sides.
• Subtract 11 to both sides.
