Решите уравнения 4(3-2x)+24=2(3+2x) 0,2(5y-2)=0,3(2y-1)-0,9

Решите задачу:

$4(3 - 2x) + 24 = 2(3 + 2x) \\ 12 - 8x + 24 = 6 + 4x \\ - 8x + 36 = 6 + 4x \\ - 8x - 4x = 6 - 36 \\ - 12x = - 30 \\ x = \frac{ - 30}{ - 12} \\ x = \frac{5}{2} \\ x = 2.5$
$0.2(5y - 2) = 0.3(2y - 1) - 0.9 \\ y - 0.4 = 0.6y - 0.3 - 0.9 \\ y - 0.4 = 0.6y - 1.2 \\ y - 0.6y = - 1.2 + 0.4 \\ 0.4y = - 0.8 \\ y = - 0.8 \div 0.4 \\ y = - 8\div 4 \\ y = - 2$
