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
