22.5 (shower) = X (variable used in place of the amount of water she uses to wash clothes) - 7.5 (the amount she used in the shower is 7.5 gallons less than she uses for washing clothes)
22.5 = X - 7.5 《 This is the equation.
Solve is by adding 7.5 to both sides to cancel out the negative 7.5 and you get (X = 30). Hope this helps.

Step-by-step explanation:
if we have 137 students, and out of this number 7 were in cars

26 students in each bus
2/x^8-y^8 =2/(x^4-y^4)^2=2/(x^4-y^4) * 1/(x^4-y^4)
