Hon Alg 2: Unit 6 SYSTEMS OF EQUATIONS A system of equations
... STEP #1: Put both equations in SAME FORM (Ax + By = C) STEP #2: SELECT A VARIABLE to eliminate (x or y) STEP #3: As needed, make that variable in both equations have same coefficients and opposite signs (ex: -3x and 3x) by MULTIPLICATION to each equation. (LCM can help) STEP #4: ADD the two equation ...
