Answer: x=6

Step-by-step explanation:

To solve for x, we want to isolate the variable.

\frac{5x+6}{8} +\frac{5x+4}{4} =13        [get common denominator]

\frac{5x+6}{8} +\frac{2(5x+4)}{8} =13     [add fractions]

\frac{5x+6+10x+8}{y} =13          [combine like terms]

\frac{15x+14}{8} =13                 [multiply both sides by 8]

15x+14=104            [subtract both sides by 14]

15x=90\\                      [divide both sides by 15]

x=6

Now, we know that x=6.
