2. Like Terms:

Vocabulary:

In algebraic expressions & equations, like terms are terms that contain the same variables raised to the same power. Only the coefficients of like terms can be different.

1. Coefficient:

Examples include: 7x x -2x

()xy2 -2y2x 6xy2

Adding & Subtracting like terms is just combining the coefficients.3x - 2x = 2x2 + 5x =

Translating Expressions

Practice Problems: Translating Equations

1. Buck has $20 more than Roger. Together they have $90.

How much does each one have?

2. Peter has $6 more than Meg. Chris has $18 more than Peter. They have $84 all together. How much does each one have?

3. The sum of 3 consecutive numbers is 87. What are the three numbers?

Key Concept: Always Assign the variable to the smallest, least, lightest, shortest, etc. Every other number is shown by its relationship to the variable.

4. Jay worked 6 hours less than May. Together they worked 64 hours. How many hours did each work?

Solving One-Step Equations:

1. n + 6 = 12

Pencils Down; Mental Math Only!!

2. 56 = 7x

3. y - 17 = 41

4. = 4 **6. = 45. 8m = 48
