5x-7y = 10
-7y = 10-5x
y = -(10-5x/7)
y = 5x-10/7

if we take the x=1, then
y = 5(1)-10/7
y = 35-10/7
y=25/7

like this we can take the values of x, to get the value of 'y' according to the number taken in the place of 'x'

7y = -(10-5x/7)
y = 5x-10/7

put the value of x = 1 ,,then
y = 5.1-10/7
y = 35-10/7
y = 25/7
