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 =

Labc is reflected across x = 1 and y = -3. what are the coordinates of the reflection image of a after both reflections?

3x + 4y = 5 x- 3y = -7 solve by substitution
