Answer 1

Answer:

x=6.5 , y= 3.5

Step-by-step explanation:

x+y-8/2 = x+2y-14/3

3(x+y-8) = 2(x+2y-14)

3x +y-24=2x+4y-28

3x-2x+y-4y= -28+24

x-3y= -4 _________(1)

x+y-8/2=3x+y-12/11

11(x+y-8)=2(3x+y-12)

11x+11y-88=6x+2y-24

11x-6x+11y-2y= -24+88

5x+9y = 64 ____________(2)

multiply 3 to equation (1)

3x-9y= -12________(3)

add. equation (2),(3)

5x+9y=64

+ 3x-9y = -12

____________

8x = 52

x=52/8

x=6.5

put value of x in equation (1)

x-3y= -4

6.5-3y = -4

-3y= -4-6.5

-3y= -10.5

3y=10.5

y=10.5/3

y=3.5
