Question

find 2/5x-3/7-1/14-3/7*3/5​

Answer 1

Answer:

$\frac{28-53x}{70x}$

Step-by-step explanation:

The Given Equation:  $\frac{2}{5x}-\frac{3}{7} - \frac{1}{14} -\frac{3}{7}*\frac{3}{5}$

= $\frac{2}{5x} - \frac{3}{7} -\frac{1}{14} -\frac{3*3}{7*5}$

= $\frac{2}{5x} -\frac{3}{7} -\frac{1}{14} -\frac{9}{35}$

= $\frac{((\frac{70x}{5x})*2)-((\frac{70x}{7} )*3)-((\frac{70x}{14} )*1)-((\frac{70x}{35} )*9)}{70x}$

= $\frac{(14*2)-(10x*3)-(5x*1)-(2x*9)}{70x}$

= $\frac{28-30x-5x-18x}{70x}$

= $\frac{28-x(30+5+18)}{70x}$

= $\frac{28-53x}{70x}$

Hope you understand the process...
