  1. 7-2D: Write & Solve Division Equations Reteach Homework • a=8 • g=50 5. t=27 • r=35 • k=49 • h=48 • r=143 • q=168 • y=170 • r=23.5 • r=0.57 • c=1.96 • c=2,862 years

  2. 7-3B: Solve & Write Two-Step Equations Target: Write and solve two-step linear equations.

  3. Vocabulary • Two-step equation – an equation with two different operations. To solve a two-step equation, undo the operations in reverse PEMDAS.

  4. Ex. 1: Solve a Two-Step Equation • Solve 2x+3=11. Check your solution. • Subtract 3 from both sides of the equation. • Divide both sides of the equation by 2. • Check your work!

  5. Practice This! • 3x+6=18 • 3n+4=13

  6. Ex. 2: Solve a Two-Step Equation • Solve 3y-8=7. Check your solution. • Add 8 to both sides. • Divide each side by 3. • Check your work!

  7. Ex. 3: Solve A Two-Step Equation • Solve 9+6b=51. Check your work! • Subtract 9 from both sides of the equation. • Divide both sides of the equation by 6. • Check your work!

  8. Practice This! • 5x-4=16 • 8+7m=50

  9. Real World Example • At Superplay USA, a hamburger meal costs $4.50 and each round of bowling costs $2.50. If you have $22.00, how many rounds can you play if you buy a meal? • Key Words: hamburger meal, bowling, $22.00 • Variable: b for bowling • Equation: 4.50+2.50b=22.00 • Subtract 4.50 from both sides. • Divide each side by 2.50. • Check your work.

  10. Practice This! • Nadia bought a necklace for $8.50 and some earrings that cost $3.75 for each pair. The total cost was $19.75. Write and solve an equation to find how many pairs of earrings Nadia bought.
