Solve {l}{15={(10/100)}*x}{y=20.65}{z=y}{a=z}{text{Solvefor}btext{where}}{b=a}

$$\left. \begin{array} { l } { 15 = {(\frac{10}{100})} \cdot x }\\ { y = 20.65 }\\ { z = y }\\ { a = z }\\ { \text{Solve for } b \text{ where} } \\ { b = a } \end{array} \right.$$

Solve for x, y, z, a, b

$$b=20.65$$

Solution Steps

Consider the first equation. Reduce the fraction \frac{10}{100} to lowest terms by extracting and canceling out 10.

$$15=\frac{1}{10}x$$

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

$$\frac{1}{10}x=15$$

Multiply both sides by 10, the reciprocal of \frac{1}{10}.

$$x=15\times 10$$

Multiply 15 and 10 to get 150.

$$x=150$$

The system is now solved.

$$x=150 y=20.65 z=20.65 a=20.65 b=20.65$$
