More 2-Step Equations

Today's agenda: solve 2-step equations

Solving 2-Step Equations

13 = 4.5 - 5k

Solve for k

*requires working backwards through the order of operations using inverse operations.

Solving 2-Step Equations

Solve for x

3x - 9 = 6

Reorder

Order the steps to solve: 12 + 7h = 5

• Subtract 12 from both sides.

• Divide both sides by 7.

• Simplify to find the solution. (Hint: h=?)
