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
