Solve 9p_{5}+5*p_{4}=10p_{y}

$$9 p _ { 5 } + 5 \cdot p _ { 4 } = 10 p _ { y }$$

Solve for p_4

$$p_{4}=-\frac{9p_{5}}{5}+2p_{y}$$

Steps for Solving Linear Equation

Subtract 9p_{5} from both sides.

$$5p_{4}=10p_{y}-9p_{5}$$

Divide both sides by 5.

$$\frac{5p_{4}}{5}=\frac{10p_{y}-9p_{5}}{5}$$

Dividing by 5 undoes the multiplication by 5.

$$p_{4}=\frac{10p_{y}-9p_{5}}{5}$$

Divide 10p_{y}-9p_{5} by 5.

$$p_{4}=-\frac{9p_{5}}{5}+2p_{y}$$

Solve for p_5

$$p_{5}=\frac{10p_{y}-5p_{4}}{9}$$

Steps for Solving Linear Equation

Subtract 5p_{4} from both sides.

$$9p_{5}=10p_{y}-5p_{4}$$

Divide both sides by 9.

$$\frac{9p_{5}}{9}=\frac{10p_{y}-5p_{4}}{9}$$

Dividing by 9 undoes the multiplication by 9.

$$p_{5}=\frac{10p_{y}-5p_{4}}{9}$$
