OBJECTIVE: Students will solve multistep equations.
AIM: How do we solve multistep equations using the distributive property, combining like terms, and moving variables to one side of the equation?
STANDARDS: 7.A.4
PRIOR KNOWLEDGE: Given the expression 5y + 7
What do we call 5y and 7? __________
7 is a _________
y is a _________
5 is a _________

2. MINI LESSON:
An equation is a mathematical sentence using an equal sign
Examples: -5x = 16x2 z = = 5
________________________________________________
Solve the equation 9n + 36 = 54
Strategy isolate n
Step 1 Subtract 36 from both sides of the equation
Step 2 Do the math

3. Step 3 Divide both sides of the equation by 9
Step 4 Do the math
Solution:
Another way…Flowcharts!

4. Solve the equation -2n + 7(n – 5) = 105
Step 1 Use the distributive property to multiply 7(n – 5)
Step 2 Rewrite the equation
Step 3 Add the like terms

5. Step 4 Add 35 to both sides
Step 5 Divide both sides by 5
Solution:
Another way with Flowcharts

6. HOMEWORK:
Solve the equations
5n – 50 = 120
-15 + y + 5 = 75
4b + 9b - 2b = 132
5t – 2(t – 3) = 33
N – 4 = -6 18
