\left(-14-\sqrt{2}\right)x=5
Combine all terms containing x.
\left(-\sqrt{2}-14\right)x=5
The equation is in standard form.
\frac{\left(-\sqrt{2}-14\right)x}{-\sqrt{2}-14}=\frac{5}{-\sqrt{2}-14}
Divide both sides by -14-\sqrt{2}.
x=\frac{5}{-\sqrt{2}-14}
Dividing by -14-\sqrt{2} undoes the multiplication by -14-\sqrt{2}.
x=\frac{5\sqrt{2}}{194}-\frac{35}{97}
Divide 5 by -14-\sqrt{2}.
