1. Equations
Chapter 7.1

2. What is the difference between an expression and an equation?
An equation has an EQUALS sign in the problem!
Expression :
Equation : = 11
Algebraic Expression : x + 5
Algebraic Equation : x + 5 = 10

3. Solve each equation from the list given.
9 + w = 17 7, 8, or 9
d – 11 = 5
14, 15, or 16
2y = 4
2, 3, or 4

4. Find each solution mentally
j + 7 = 13
j = 6
m = 13
4 + m = 17
p – 2 = 19
p = 21
b = 3
15 – b = 12
Addition can ALWAYS be solved using the OPPOSITE math, but Subtraction can’t!

5. Find each solution mentally
Multiplication can ALWAYS be solved using the OPPOSITE math, but Division can’t!
