-4x-3=\sqrt{2} -4x-3=-\sqrt{2}
Take the square root of both sides of the equation.
-4x-3-\left(-3\right)=\sqrt{2}-\left(-3\right) -4x-3-\left(-3\right)=-\sqrt{2}-\left(-3\right)
Add 3 to both sides of the equation.
-4x=\sqrt{2}-\left(-3\right) -4x=-\sqrt{2}-\left(-3\right)
Subtracting -3 from itself leaves 0.
-4x=\sqrt{2}+3
Subtract -3 from \sqrt{2}.
-4x=3-\sqrt{2}
Subtract -3 from -\sqrt{2}.
\frac{-4x}{-4}=\frac{\sqrt{2}+3}{-4} \frac{-4x}{-4}=\frac{3-\sqrt{2}}{-4}
Divide both sides by -4.
x=\frac{\sqrt{2}+3}{-4} x=\frac{3-\sqrt{2}}{-4}
Dividing by -4 undoes the multiplication by -4.
x=\frac{-\sqrt{2}-3}{4}
Divide \sqrt{2}+3 by -4.
x=\frac{\sqrt{2}-3}{4}
Divide -\sqrt{2}+3 by -4.
x=\frac{-\sqrt{2}-3}{4} x=\frac{\sqrt{2}-3}{4}
The equation is now solved.
