Which expression is equivalent to7_/x^2 ÷ 5_/y^3? assume y# 0

Follow these steps using the algebra tiles to solve the equation −5x + (−2) = −2x + 4. 1. add 5 positive x-tiles to both sides and create zero pairs. 2. add 4 negative unit tiles to both sides and create zero pairs. 3. divide the unit tiles evenly among the x-tiles. x =

For what values of x is x2 + 2x = 24 true?
