Question

Solve by using cross multiplication method:- x+1/2 + y-1/3=8. x-1/3 + y+1/2 = 9

Answer 1

Answer:

x=7; y=13

Step-by-step explanation:

x+1/2 + y-1/3 = 8

then we can arrange proper equation,

3x+2y=47.

2nd equation is x-1/3 + y+1/2 = 9.

then 2x+3y=53.

solve the 2 equation

i.e

3x+2y=47 (×2)

2x+3y=53 (×3)

then

6x+4y=94

6x+9y=159

____________

-5y= -65

y=13.

substitute the y value in 1st equation,

3x+26=47

x=7.

the answer is (x,y) = (7,13).
