Question 158854
by substituting the values of x and y in the equation we get the expression


{7-(1/7) }          /          {10 . (2/7)}

numerator                       denominator



Taking the lcm for the numerator, we get (48/7).  

When it comes to the denominator, multiplying 10 with (2/7) gives 20/7

So the total expression is (48/7) / (20/7) = (48/7) * (7/20) = 48/20 = 12/5.

So the answer is 12/5
