Equations with Fractions

Solve for $x$:

  1. $\dfrac{x}{2}=17 \rightarrow \mathbf{x=34}$
  2. $\dfrac{x}{3}=\dfrac{2}{5}\rightarrow \mathbf{x=\dfrac{6}{5}}$
  3. $\dfrac {1}{2}+x=4 \rightarrow \mathbf{x=3.5}$
  4. $ x-\dfrac{2}{7}=10\rightarrow \mathbf{x=10\dfrac{2}{7}}$
  5. $\dfrac{x}{10}+9=12\rightarrow \mathbf{x=30}$
  6. $\dfrac{20}{x}=4\rightarrow \mathbf{x=5}$
  7. $\dfrac{12}{x}-4=20\rightarrow \mathbf{x=\dfrac{1}{2}}$
  8. $1-\dfrac{5}{x}=16\rightarrow \mathbf{x=\dfrac{-1}{3}}$
  9. $(\dfrac{x}{3})^2=25\rightarrow \mathbf{x=15}$
  10. $(\dfrac{7}{x})^2=64\rightarrow \mathbf{x=\dfrac{7}{8}}$
