Question 179590: Solve the system of equations using the addition (elimination) method.
If the answer is a unique solution, present it as an ordered pair: (x, y). If not, specify whether the answer is "no solution" or "infinitely many solutions" and state how you arrived at that conclusion.
3x - 11y = 9
-9x + 33y = -27
Answer by checkley77(12844) (Show Source): You can put this solution on YOUR website!
3x-11y=9 MULTIPLY BY 3 & ADD.
-9x+33y=-27
9X-33Y=27
-----------------
0+0=0
THESE TWO EQUATIONS ARE EQUAL (THE SAME) WITH 2 UNKNOWNS THUS INFINITELY MANY SOLUTIONS.
-11Y=-3X+9 OR Y=-3X/-11+9/-11 OR Y=3X/11-9/11
-9X-33Y=27 OR -33Y=9X+27 OR Y=9X/-33+27/-33 OR Y=3X/11-9/11
