7. A little vocab… Variable:
symbols, usually letters, that represent unknown values
Numerical expressions:
consists of numbers, operations, and grouping symbols.
Algebraic expressions:
expressions that contain at least one variable
Evaluate an Expression:
x(x-3) + 2 when x = 5
3x²- 2x when x = -2

8. Like Terms- Terms that have the same variable parts
Simplify the expression.
x + 2x
3+ 8m + 3m – 2
y² + 3y² + 2y
d. 3(2n – 6) + 4

9. Solving equations with variable on one side
Solve.
f. 20y + 3 = 13
a. 2x + 8 = 16
g n= 8
b. 3w - 29 = 4
h. 18 – 3x = 1
c. -4n + 27 = 3
i. 13 = 4 – 6m
d. -7k - 13 = 8
