Find the solutions of pair of linear equations :-4x+5y + 13 and 2x-2y – InterviewSolution

1.

Find the solutions of pair of linear equations :-4x+5y + 13 and 2x-2y = 2OR

Answer»

4x+5y= -13 (equation 1)

2x-2y= 2 ( equation 2)

Multiply equation 2 by 2

4x-4y= 44x+5y= -13Solve both the equationy= -9substitute value of y in equation 22x-2(-9) = 22x +18 = 22x = -16x= -8
