Step-by-step explanation:
Solving for x...

Times the

, both the numerator and denominator, by 8 to get the denominator to 16.
Times the

, both the numerator and denominator, by 4 to get the denominator to 16.
Then rewrite the problem,

now that the denominators are all the same, you can solve...
subtract the

from both sides
you should get

Multiply both sides by 16 (it'll cancel both the 16 out making it go away)
8x = 11
divide each side by 8 to have the x alone
<u>8x</u> = <u>11
</u> 8 8
<u>
</u> You should end with x =

or 1.375<u>
