Solve for x. Round to the nearest tenth, if necessary.

Which expression is equivalent to 2x^2+2x-4/2x^2-4x+2

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 =
