Applicare la formula: $x+a\geq b$$=x\geq b-a$, dove $a=-\frac{3}{5}$ e $b=19$

Applicare la formula: $\frac{a}{b}c$$=\frac{ca}{b}$, dove $a=-3$, $b=5$, $c=-1$, $a/b=-\frac{3}{5}$ e $ca/b=- -\frac{3}{5}$

Applicare la formula: $\frac{a}{b}+c$$=\frac{a+cb}{b}$, dove $a/b+c=19+\frac{3}{5}$, $a=3$, $b=5$, $c=19$ e $a/b=\frac{3}{5}$

Applicare la formula: $ab$$=ab$, dove $ab=19\cdot 5$, $a=19$ e $b=5$

Applicare la formula: $a+b$$=a+b$, dove $a=3$, $b=95$ e $a+b=3+95$
