2\left(\frac{\sqrt{2}}{2}+1\right)R=4h
Multiply both sides of the equation by 2.
\left(2\times \frac{\sqrt{2}}{2}+2\right)R=4h
Use the distributive property to multiply 2 by \frac{\sqrt{2}}{2}+1.
\left(\frac{2\sqrt{2}}{2}+2\right)R=4h
Express 2\times \frac{\sqrt{2}}{2} as a single fraction.
\left(\sqrt{2}+2\right)R=4h
Cancel out 2 and 2.
\frac{\left(\sqrt{2}+2\right)R}{\sqrt{2}+2}=\frac{4h}{\sqrt{2}+2}
Divide both sides by \sqrt{2}+2.
R=\frac{4h}{\sqrt{2}+2}
Dividing by \sqrt{2}+2 undoes the multiplication by \sqrt{2}+2.
R=-2\sqrt{2}h+4h
Divide 4h by \sqrt{2}+2.
2\left(\frac{\sqrt{2}}{2}+1\right)R=4h
Multiply both sides of the equation by 2.
\left(2\times \frac{\sqrt{2}}{2}+2\right)R=4h
Use the distributive property to multiply 2 by \frac{\sqrt{2}}{2}+1.
\left(\frac{2\sqrt{2}}{2}+2\right)R=4h
Express 2\times \frac{\sqrt{2}}{2} as a single fraction.
\left(\sqrt{2}+2\right)R=4h
Cancel out 2 and 2.
\sqrt{2}R+2R=4h
Use the distributive property to multiply \sqrt{2}+2 by R.
4h=\sqrt{2}R+2R
Swap sides so that all variable terms are on the left hand side.
\frac{4h}{4}=\frac{\sqrt{2}R+2R}{4}
Divide both sides by 4.
h=\frac{\sqrt{2}R+2R}{4}
Dividing by 4 undoes the multiplication by 4.
h=\frac{\sqrt{2}R}{4}+\frac{R}{2}
Divide R\sqrt{2}+2R by 4.
