HW#1-Two Step Equations
1.) 7y – 4 = 10 2.) -4 = 7 – w (if you don’t like the variable on the right,
switch the eqn 7 – w = -4)

SWBAT… solve multi-step equations
Agenda
1. Warm-up (10 min)
2. Review hw#4 (10 min)
3. Solving multi-step equations w/ distr property and CLT: 4 problems (20 min)
4. Start HW#2 (5 min)

Test Corrections: Common spelling/ grammar mistakes
1. “I” should be capitalized
2. It’s “supposed” not suppose
3. It’s “plugged” not pluged
4. It’s “parenthesis”
5. It’s “going to” not gonna1. Even worse is “imma gonna”
6. Your vs. you’re
7. Their vs. there
Solve the equation: List the steps:
2.) 1. Cross multiply 3(k+3) = 9(5)
2. Distribute the 3
3. Subtract both sides by 9
k = 12
4. Divide both sides by 3

Multiply both sides of the equation by 6
To remove fractions from an equation:Multiply both sides of the equation (EVERY TERM) by the least common denominator
3.)
Solving linear equations with variables on both sides
Our goal is to collect the variable terms on one side of the equation and the numbers on the other side.
1.) -6b + 1 = -3 + 2b
2.) 2(r + 4) – 2 = (12r + 18) 3
