Solve 4s=2U_{0}+20

$$4 s = 2 U _ { 0 } + 20$$

Solve for U_0

$$U_{0}=2\left(s-5\right)$$

Steps for Solving Linear Equation

Swap sides so that all variable terms are on the left hand side.

$$2U_{0}+20=4s$$

Subtract 20 from both sides.

$$2U_{0}=4s-20$$

Divide both sides by 2.

$$\frac{2U_{0}}{2}=\frac{4s-20}{2}$$

Dividing by 2 undoes the multiplication by 2.

$$U_{0}=\frac{4s-20}{2}$$

Divide -20+4s by 2.

$$U_{0}=2s-10$$

Solve for s

$$s=\frac{U_{0}+10}{2}$$

Steps for Solving Linear Equation

The equation is in standard form.

$$4s=2U_{0}+20$$

Divide both sides by 4.

$$\frac{4s}{4}=\frac{2U_{0}+20}{4}$$

Dividing by 4 undoes the multiplication by 4.

$$s=\frac{2U_{0}+20}{4}$$

Divide 20+2U_{0} by 4.

$$s=\frac{U_{0}}{2}+5$$
