Solve {l}{x=4}{y=5{(x+1)}}{z=5*6}{text{Solvefor}a,btext{where}}{a=y}{b=z}

$$\left. \begin{array} { l } { x = 4 }\\ { y = 5 {(x + 1)} }\\ { z = 5 \cdot 6 }\\ { \text{Solve for } a,b \text{ where} } \\ { a = y }\\ { b = z } \end{array} \right.$$

Solve for x, y, z, a, b

$$a=25$$

$$b=30$$

Solution Steps

Consider the second equation. Insert the known values of variables into the equation.

$$y=5\left(4+1\right)$$

Add 4 and 1 to get 5.

$$y=5\times 5$$

Multiply 5 and 5 to get 25.

$$y=25$$

Consider the third equation. Multiply 5 and 6 to get 30.

$$z=30$$

Consider the fourth equation. Insert the known values of variables into the equation.

$$a=25$$

Consider the fifth equation. Insert the known values of variables into the equation.

$$b=30$$

The system is now solved.

$$x=4 y=25 z=30 a=25 b=30$$
