$- 4 + x = 12 \\ x = 12 + 4 \\ x = 16$

$0.5x = - 0.3 \\ x = - 0.3 \div 0.5 \\ x = - 3 \div 5 \\ x = - 0.6$

$- \frac{5}{8} x = \frac{15}{16} \\ x = \frac{15}{16} \div ( - \frac{5}{8} ) \\ x = - \frac{15 \times 8}{16 \times 5} \\ x = - \frac{3}{2} \\ x = - 1 \frac{1}{2} \\ x = - 1.5$

$12(x + 5) = - 24 \\ 12x + 60 = - 24 \\ 12x = - 24 - 60 \\ 12x = - 84 \\ x = - 84 \div1 2 \\ x = - 7$

$3(6 - x) - 2(x - 5) = 63 \\ 18 - 3x - 2x + 10 = 63 \\ - 5x = 63 - 28 \\ - 5x = 35 \\ x = 35 \div ( - 5) \\ x = - 7$
