Adjust Fractions based on the LCM

= \frac{15 c}{5 ( c - 4 )} - \frac{2 ( c - 4 )}{5 ( c - 4 )}

Apply the fraction rule:

\frac{a}{c} - \frac{b}{c} = \frac{a - b}{c}

= \frac{15 c - 2 ( c - 4 )}{5 ( c - 4 )}

Simplify

15 c - 2 (c - 4) : 13 c + 8

= \frac{13 c + 8}{5 ( c - 4 )}

\frac{3}{5} - \frac{1}{3} = \frac{x}{9}

x + 4 x + (x - 8) = 100

4 y + 3 = 19

(- \frac{15}{4}) + \frac{7}{9}

(5 x - 3)^{2} > - 2
