Answer 2

Answer:

x/3+y/4=11

=>( 4x+3y)/12=11

=> 4x+3y=11×12=132

=> 4x=132-3y

=> x=(132-3y)/4

again,

5x/6-y/3= -7

=> (5x-2y)/6= -7

=> 5x-2y= -7×6= -42

=> 5x=2y-42

=> x=(2y-42)/5

so,

(2y-42)/5=(132-3y)/4

=> 4(2y-42)=5(132-3y)

=> 8y-168=660-15y

=> 8y+15y=660+168

=> 23y=828

=> y=828/23

=> y=36

x=(2y-42)/5

=> x=(2.36-42)/5

=> x=(72-42)/5

=> x=30/5

=> x=6

so,x=6 and y=36
