Solve {l}{8*y+13=73-1*2*y}{z=2}{text{Solvefor}atext{where}}{a=z}

$$\left. \begin{array} { l } { 8 \cdot y + 13 = 73 - 1 \cdot 2 \cdot y }\\ { z = 2 }\\ { \text{Solve for } a \text{ where} } \\ { a = z } \end{array} \right.$$

Solve for y, z, a

$$a=2$$

Solution Steps

Consider the first equation. Multiply 1 and 2 to get 2.

$$8y+13=73-2y$$

Add 2y to both sides.

$$8y+13+2y=73$$

Combine 8y and 2y to get 10y.

$$10y+13=73$$

Subtract 13 from both sides.

$$10y=73-13$$

Subtract 13 from 73 to get 60.

$$10y=60$$

Divide both sides by 10.

$$y=\frac{60}{10}$$

Divide 60 by 10 to get 6.

$$y=6$$

The system is now solved.

$$y=6 z=2 a=2$$
