Solve for x.<br> 13<br> =(5x+ 6)/8 + <br> (5x+4)/4

valkas [14]

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.
