5x = -60; -10x = 8; 7x = 9; 6x = -50; -9x = -3; 0,5x = 1,2; 0,7x = 0; -1,5x = 6; 42x = 13.

Решаем каждое уравнение, деля обе части на коэффициент при $x$.

1. $5x=-60$ → $x=\frac{-60}{5}=-12$.

2. $-10x=8$ → $x=\frac{8}{-10}=-\frac{4}{5}=-0{,}8$.

3. $7x=9$ → $x=\frac{9}{7}\approx1{,}285714\ldots$.

4. $6x=-50$ → $x=\frac{-50}{6}=-\frac{25}{3}\approx-8{,}333\ldots$.

5. $-9x=-3$ → $x=\frac{-3}{-9}=\frac{1}{3}\approx0{,}333\ldots$.

6. $0{,}5x=1{,}2$ → $x=\frac{1{,}2}{0{,}5}=\frac{12}{5}=2{,}4$.

7. $0{,}7x=0$ → $x=\frac{0}{0{,}7}=0$.

8. $-1{,}5x=6$ → $x=\frac{6}{-1{,}5}=\frac{60}{-15}=-4$.

9. $42x=13$ → $x=\frac{13}{42}\approx0{,}309523\ldots$.
