Solve the system of equations by substitution. what is the solution for x? 2x y = 1 4x 2y = -2 a. x = 0 b. x = 2 c. there is no x value as there is no solution. d. x can be any value as there is an infinite number of solutions.

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 =
