Step-by-step explanation:

8x+5y=11_____1

3x-4y=10_____2

multiply equation 1st by 3 & 2nd by 8, we get

24x+15y=33_____3

-24x-32y=80_____4 (subtract equ 4 from 3)

-___+___-_______

47y= -47

y= -47/-47

y=1

Now substituting the value of y in equation 1

8x+5y=11______1

8x+5*1=11

8x+5=11

8x=11-5

8x=6

x=6/8

x=3/4

therefore,the value of y =1 and x=3/4
