Applicare la formula: $x+a\geq b$$=x\geq b-a$, dove $a=\frac{37}{5}$, $b=-143.49$ e $x=-7.9n$

Applicare la formula: $a+b$$=a+b$, dove $a=-143.49$, $b=-\frac{37}{5}$ e $a+b=-143.49-7.4$

Applicare la formula: $ax\geq b$$=x\geq \frac{b}{a}$, dove $a=-\frac{79}{10}$, $b=-150.89$ e $x=n$

Applicare la formula: $\frac{a}{b}$$=\frac{a}{b}$, dove $a=-150.89$, $b=-\frac{79}{10}$ e $a/b=\frac{-150.89}{-7.9}$
