Answer:

1/3 or 0.3 (recurring)

Step-by-step explanation:

Let's substitute our numbers into the equation.

27 = 9x + 24 I multipled 8 by 3 in order to get 24, because x equals 3.

Now take away 24 leaving 9x on its own.

3 = 9x

Divide 9 to separate it from x.

3/9 = x

Simplify the fraction.

1/3 = x
