Jan used 22.5 gallons of water in the shower. This is 7.5 gallons less than the amount she used for washing clothes. Write and solve an equation to find the amount of water Jan used to wash clothes.

Your equation would be 22.5+7.5=x, where x is the amount of water Jan used to wash clothes. x=30 gallons of water.
