Solve the following simultaneous equations by cross-multupilationiol35 – InterviewSolution

1.	Solve the following simultaneous equations by cross-multupilationiol35. 3x + 4y = 1 0 and 2x-2y = 26 2x +3y 11 and 2x-4y-24
Answer» 2x+3y = 11 2x-4y = -24 subtraction second equation from first equation 2x+3y-2x+4y = 11+24 7y = 35 so y = 5 2x+3(5) = 11 2x+15 = 11 2x = -4 so x = -2
