Solve 8x-5/4x=9

$$8x- \frac{ 5 }{ 4 } x=9$$

Solve for x

$$x = \frac{4}{3} = 1\frac{1}{3} \approx 1.333333333$$

Steps for Solving Linear Equation

Combine 8x and -\frac{5}{4}x to get \frac{27}{4}x.

$$\frac{27}{4}x=9$$

Multiply both sides by \frac{4}{27}, the reciprocal of \frac{27}{4}.

$$x=9\times \frac{4}{27}$$

Express 9\times \frac{4}{27} as a single fraction.

$$x=\frac{9\times 4}{27}$$

Multiply 9 and 4 to get 36.

$$x=\frac{36}{27}$$

Reduce the fraction \frac{36}{27} to lowest terms by extracting and canceling out 9.

$$x=\frac{4}{3}$$
