Step-by-step explanation:4x+3y-4=4x+3y=4 equation 16x=8- 5y=6x+5y=8 equation 2comparing equation 1 with a1x+b1y=c1 weget.......a1=4,b1=3,and c1=4comparing equation 2 with a2x+b2y=c2we get.....a2=6,b2=5 c2=8d= a1/a2 ×b1/b2=4/6×3/5=4×5- 3×6=20-18=2d=2dx=c1/c2 ×b1/ b2=4/8×3/5=20-24=-4dx=-4dy=a1/a2×c1/c2=4/6×4/8=4×8-4×6=32-24=8dy=8x=dx/d=-4/2=-2y=dy/d=8/2=4(x, y) =(-2,4) is the solution for the given equation
