ocr: Solve the system 3x+4y=10 (2) (1) X-4y=1 Since the coefficients of y are opposites, eliminate y and getx. Or, multiply Eq.(2)by+3 and eliminate X to gety. Eliminate V, getx Eliminate X, gety (1)+(2)- -3-(2)+(1)- 3x+4y=10 -3x+12y=-3 X-4y=1 t 3x+4y=10 4x=11 16y=7 x-11 y-z 4 16 Elimination by Addition: Example 2
