$$( x \cdot 6.21 \% \cdot 6 ) + x = 1.8$$

Solve for x

$$x = \frac{9000}{6863} = 1\frac{2137}{6863} \approx 1.311379863$$

Steps for Solving Linear Equation

Expand \frac{6.21}{100} by multiplying both numerator and the denominator by 100.

$$x\times \frac{621}{10000}\times 6+x=1.8$$

Express \frac{621}{10000}\times 6 as a single fraction.

$$x\times \frac{621\times 6}{10000}+x=1.8$$

Multiply 621 and 6 to get 3726.

$$x\times \frac{3726}{10000}+x=1.8$$

Reduce the fraction \frac{3726}{10000} to lowest terms by extracting and canceling out 2.

$$x\times \frac{1863}{5000}+x=1.8$$

Combine x\times \frac{1863}{5000} and x to get \frac{6863}{5000}x.

$$\frac{6863}{5000}x=1.8$$

Multiply both sides by \frac{5000}{6863}, the reciprocal of \frac{6863}{5000}.

$$x=1.8\times \frac{5000}{6863}$$

Convert decimal number 1.8 to fraction \frac{18}{10}. Reduce the fraction \frac{18}{10} to lowest terms by extracting and canceling out 2.

$$x=\frac{9}{5}\times \frac{5000}{6863}$$

Multiply \frac{9}{5} times \frac{5000}{6863} by multiplying numerator times numerator and denominator times denominator.

$$x=\frac{9\times 5000}{5\times 6863}$$

Do the multiplications in the fraction \frac{9\times 5000}{5\times 6863}.

$$x=\frac{45000}{34315}$$

Reduce the fraction \frac{45000}{34315} to lowest terms by extracting and canceling out 5.

$$x=\frac{9000}{6863}$$
