Question

16/2x+3y -7/3x+2y = 1, 8/6x+9y- 21/3x+2y=10/3​ find the value of x and y

Answer 1

Answer:

x=-1/12 and y=13/48

Step-by-step explanation:

at first,

16/2x=8x 8/6x=4/3x

8x+3y-7/3x+2y=1

4/3x+9y-7x+2y=10/3

adding both,

8x-7/3x+5y=1

4/3x-7x+11y=10/3

and simplifieng them we get

1. 17/3x+5y=1
2. -17/3x+11y=10/3

adding both equations we get,

(17/3-17/3)x+16y=10/3+1

16y=13/3

y=13/48

and for x substitute y in one of equations

17/3x+5*13/48=1

17/3x=1-65/48

17/3x=-17/48

48x=-3

x=-3/48=-1/12
