3. Solve to determine the unknown variable in the equation. What are the values of x? Solve this system of equations: y = x2-3x + 12 y = -2x + 14 1. Isolate one variable in the system of equations, if needed y = x2 – 3x + 12 y = -2x + 14 2.Use substitution to create a one-variable equation. -2x + 14 = x2-3x + 12 O(-2, 1} O {-2,4} O {-1, 2} O{-1,4}
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 =
