Answer 1

Answer:

Step-by-step explanation:

X/3+y/4=11

4x+3y=132-------(1)

5x/6-y/3=-42

15x-6y=-756-------(2)

X=132-3y/4---------(from eq 1)---------3

Substitute the value of x in eq 2

15(132-3y/4)-6y = -756

After doing all operations we will get ,

Y=-5104/-69

Y= 73.9 approx

Substitute the value of y in eq 3 ,

X= 132-3×73.9/4

X= -59.7/4

X= -14.9 approx
