Developing mathematical problem solving skills is one of the main goals of school . Chapter 7.3. Modeling - 2x + 3 = 11. =. Each one has 4 squares, so 4 is your answer!. Solving 2-Step Equations. Algebraic equations are solved backwards, so do the OPPOSITE math!. Since there are more than 1 steps to do you must follow the Order of Operations…but BACKWARDS!!!. Solve:. LINEAR . QUADRATIC . QUADRATIC . Quadratic Equations. Solve:. a) b) . . Learning Log Summary . LT. . 1. . – I can . solve. quadratic equations using factoring or the square root method.. Substitution and Elimination. Elimination. Arrange the equations in STANDARD FORM. . . Your goal is to find a way to eliminate one of the variables so you can solve a one-variable equation.. . 21. (. 5-. 6. ).
