Math Problem Solver

Simplified:

$$7.21 x + 1.12 - 4.53 x = \frac{67 x}{25} + \frac{28}{25}$$

$$\begin{aligned}x \left(7 + 21 \cdot \frac{1}{100}\right) + 1 + 12 \cdot \frac{1}{100} - x \left(4 + 53 \cdot \frac{1}{100}\right)&=\frac{721 x}{100} + \frac{28}{25} - x \left(4 + \frac{53}{100}\right)\\&=\frac{721 x}{100} + \frac{28}{25} - \frac{x 453}{100}\\&=\frac{721 x}{100} + \frac{\left(-453\right) x}{100} + \frac{28}{25}\\&=\frac{67 x}{25} + \frac{28}{25}\end{aligned}$$
