Steps for Solving Linear Equation

Multiply \frac{3}{5} times -\frac{3}{4} by multiplying numerator times numerator and denominator times denominator.

$$\frac{3\left(-3\right)}{5\times 4}=\frac{A\pi }{-\frac{3}{5}}\times 4$$

Do the multiplications in the fraction \frac{3\left(-3\right)}{5\times 4}.

$$\frac{-9}{20}=\frac{A\pi }{-\frac{3}{5}}\times 4$$

Fraction \frac{-9}{20} can be rewritten as -\frac{9}{20} by extracting the negative sign.

$$-\frac{9}{20}=\frac{A\pi }{-\frac{3}{5}}\times 4$$

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

$$\frac{A\pi }{-\frac{3}{5}}\times 4=-\frac{9}{20}$$

Divide both sides by 4.

$$\frac{A\pi }{-\frac{3}{5}}=\frac{-\frac{9}{20}}{4}$$

Express \frac{-\frac{9}{20}}{4} as a single fraction.

$$\frac{A\pi }{-\frac{3}{5}}=\frac{-9}{20\times 4}$$

Multiply 20 and 4 to get 80.

$$\frac{A\pi }{-\frac{3}{5}}=\frac{-9}{80}$$

Fraction \frac{-9}{80} can be rewritten as -\frac{9}{80} by extracting the negative sign.

$$\frac{A\pi }{-\frac{3}{5}}=-\frac{9}{80}$$

Multiply both sides by -\frac{3}{5}.

$$A\pi =-\frac{9}{80}\left(-\frac{3}{5}\right)$$

Multiply -\frac{9}{80} times -\frac{3}{5} by multiplying numerator times numerator and denominator times denominator.

$$A\pi =\frac{-9\left(-3\right)}{80\times 5}$$

Do the multiplications in the fraction \frac{-9\left(-3\right)}{80\times 5}.

$$A\pi =\frac{27}{400}$$

The equation is in standard form.

$$\pi A=\frac{27}{400}$$

Divide both sides by \pi .

$$\frac{\pi A}{\pi }=\frac{\frac{27}{400}}{\pi }$$

Dividing by \pi undoes the multiplication by \pi .

$$A=\frac{\frac{27}{400}}{\pi }$$

Divide \frac{27}{400} by \pi .

$$A=\frac{27}{400\pi }$$
