$\frac{1}{2} x + x = 42 \\ \\ ⇒  \: \frac{1x}{2} + x = 42 \\ \\ ⇒  \: \frac{x}{2} + x = 42 \\ \\ ⇒  \: 2( \frac{x}{2} + x) = 2.42 \\ \\ Distribute \\ Cancel \: multiplied \: terms \: that \: are \: in \: the \: denominator \\ Combine \: like \: terms \\ Multiply \: the \: numbers \\ \\ ⇒  \: 3x = 84 \\ \\ ⇒  \: \frac{3x}{3} = \frac{84}{3} \\ \\ ⇒  \: x = 28$
