$a = 16$ $a=16$

Explanation:

Given
$XXX 6 = \frac{a}{4} + 2$ $color(white)("XXX")6=a/4+2$

Subtract $2$ $2$ from both sides:
$XXX 4 = \frac{a}{4}$ $color(white)("XXX")4=a/4$

Multiply both sides by $4$ $4$
$XXX 16 = a XXX$ $color(white)("XXX")16=acolor(white)("XXX")$ or $XXX a = 16$ $color(white)("XXX")a=16$
