• 4

• 8

• -4

Solve the inequality.

x + 5x ≤ 12

• x ≥ 2

• x ≥ 7

• x ≤ 2

• x ≤ 7

An inverse operation is

• reversing the sign in an inequality

• using the opposite operation to solve equations

•  A number’s distance from zero

Like terms are 

• numbers or same variable raised to the same power

• equal numbers

• only unknown values

Choose an expression that is equivalent to the following
6n + 2(3 - 5n)

• n + 6

• 6 - 4n

• 16n + 6

Choose the first step in solving the following equation.
-3y - 12 = 14

• add 3 from both sides

• add 12 to both sides

• subtract 12 from both sides
