a = 18

Explanation:

1/6a + 4 = 7

To solve for the variable a, we have to make it by itself. First, subtract color(blue)4 from both sides of the equation:
1/6a + 4 quadcolor(blue)(-quad4) = 7 quadcolor(blue)(-quad4)

1/6a = 3

Now multiply both sides by color(blue)6:
1/6a color(blue)(*6) = 3 quadcolor(blue)(*quad6)

Therefore,
a = 18

Hope this helps!
