6b²7a(2b³a²)

84b⁵a³

400

Simplify:

6x(4x² + 7x + 3)

24x³ + 42x + 18x

500

Simplify the following expression: 

3x(4x² + 2x) - (12x + 2x³)  

Then solve for when x = 1

10x³ + 6x² - 12x

10(1)³ + 6(1)² - 12(1) = 4

Solve for k: 

7(9 + k) = 84

k = 3

Solving multi-step equations

100

Solve for k: 

3k + 5 - 2k = 14

k = 9

200

Solve for y:

Equations vs expressions 

(clue, equations usually are used for "solve for x" questions and expressions usually used for "substitute for x" questions 

Expressions are math phrases that never have an equal sign.

Equations are math phrases that always have an equal sign.
