Question

Solve the following pair of equations for x and y: 4x + 6/y = 15, 6x – 8/y = 14

Answer 1

Step-by-step explanation:

by eliminationmethod,

multiply 6 in 1st equation and 4 in 2nd equation

6(4x+6/y=15)

4(6x-8/y=14)

24x+36/y=90

24x-32/y=56

change the sign

68/y=34

34y=68

y=2

substitute y in equation 1

you get x=3
