What is the length of the unknown leg in the right triangle ?

Solve the given system of equations. 2y= -x+9 , 3x-6= -15

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 =
