Work Step by Step

We start by creating a common denominator for all of the fractions: $\frac{5}{20}+\frac{16x}{20}=\frac{11}{20}$ We now can combine the denominators on the same side of the equation: $\frac{16x+5}{20}=\frac{11}{20}$ We then multiply both sides by 20 to find: $16x+5=11$ We subtract 5 and divide by 16 to obtain that $x=6/16$, which equals 3/8. We plug 3/8 in for x and confirm that our answer is, indeed, correct.
