Expressions Equations

Like terms are 

• numbers or same variable raised to the same power

• equal numbers

• only unknown values

One difference between equations and expressions would be...

• you solve both of them using inverse operations.

• you flip the symbol when you multiply or divide by a negative

• equations have an equals because they show two equal expressions. Expresions have terms and operations.

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
