How To Solve Two-Step Equations

• First, circle the variable with its coefficient

• Isolate the variable by adding/subtracting the constant

• Multiply or Divide to get the variable all by itself

 $2x+4=10$  

Multiple Choice

What do I do first in 3x - 10 = 14

• Divide both sides by 3

• Add 10 to both sides

• Multiply both sides by 3

• Subtract 10 to both sides

Multiple Choice

Now we are left with 3x = 24, what do we do next?

• Multiply both sides by 3

• Divide both sides by 3

Multiple Choice

What is our final answer?

• x = 8

• x = 72

• x = 21

 $\frac{x}{5}+5=-3$
