I think of a number and add one fourth of it to half of it and the result is twelve. What is the number I thought of?

belka [17]

Suppose that the number u were thinking about is x thus :

$\frac{1}{4} x + \frac{1}{2} x = 12 \\$

Multiply both sides by 4

$4 \times ( \frac{1}{4} x + \frac{1}{2} x) = 4 \times 12 \\$

$x + 2x = 48$

$3x = 48$

Divide both sides by 3

$\frac{3x}{3} = \frac{48}{3 } \\$

$x = 16$
