x in the Bottom

When x sits in a bottom, clear it the same way: multiply by the bottom. In $\frac{3}{x}+\frac{1}{2} = 2$, multiply both sides by x. The x cancels from $\frac{3}{x}$, and the other terms are multiplied by x:

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

The bottom left is a number, cleared as before: times 2 gives $6+x = 4x$, so 3x is 6 and x is 2. But something is new. The original equation has no value at x = 0, since $\frac{3}{0}$ means nothing. Multiplying by x is only safe when x is not 0, so an answer must be checked in the original equation: $\frac{3}{2}+\frac{1}{2}$ is 2, so x = 2 stands.

Once x stands alone, the board asks you to check it: tap Check x = 2 in the original equation.
