(2, -1) is one of many solutions to the inequality:
x – 3y < 1

With: label the vertices and all the elements needed. find x

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 =

Solve for x and y: 217x + 131y = 913; 131x + 217y = 827
