How do you solve this math problem 49over 56 equals x-1over x?

Answer 1

Starting with:

49 / 56 = (x - 1) / x

We can start with the easiest, and factor out the fraction on the left:

7 / 8 = (x - 1) / x

Now we can cross multiply the fractions on either side:

7x = 8(x - 1)

and expand:

7x = 8x - 8

then group like terms:

7x - 8x = -8

-x = -8

and finally, negate both sides:

x = 8
