2j=3\sqrt{2k+8}
The equation is in standard form.
\frac{2j}{2}=\frac{3\sqrt{2k+8}}{2}
Divide both sides by 2.
j=\frac{3\sqrt{2k+8}}{2}
Dividing by 2 undoes the multiplication by 2.
2j=3\sqrt{2k+8}
The equation is in standard form.
\frac{2j}{2}=\frac{3\sqrt{2k+8}}{2}
Divide both sides by 2.
j=\frac{3\sqrt{2k+8}}{2}
Dividing by 2 undoes the multiplication by 2.
3\sqrt{2k+8}=2j
Swap sides so that all variable terms are on the left hand side.
\frac{3\sqrt{2k+8}}{3}=\frac{2j}{3}
Divide both sides by 3.
\sqrt{2k+8}=\frac{2j}{3}
Dividing by 3 undoes the multiplication by 3.
2k+8=\frac{4j^{2}}{9}
Square both sides of the equation.
2k+8-8=\frac{4j^{2}}{9}-8
Subtract 8 from both sides of the equation.
2k=\frac{4j^{2}}{9}-8
Subtracting 8 from itself leaves 0.
\frac{2k}{2}=\frac{\frac{4j^{2}}{9}-8}{2}
Divide both sides by 2.
k=\frac{\frac{4j^{2}}{9}-8}{2}
Dividing by 2 undoes the multiplication by 2.
k=\frac{2j^{2}}{9}-4
Divide \frac{4j^{2}}{9}-8 by 2.
