If 2x + 2 = 32, solve for x.

Squaring both sides of the equation yields 2x + 2 = 94. Subtracting 2 from both sides gives 2x = 14, so x = 8.

Problem

\frac{2}{x} + 2 = \frac{3}{2}

, solve for

x

Solution

Squaring both sides of the equation yields

\frac{2}{x} + 2 = \frac{9}{4}

. Subtracting

2

from both sides gives

\frac{2}{x} = \frac{1}{4}

, so

x = 8
