Por fvr me ajude:
U=R
2y-3/4=(3-6)y+y/2

Answer 1

Resposta:

$2y - \frac{3}{4} = 3 - 6y + \frac{y}{2} \\ \frac{2y}{1} - \frac{3}{4} = \frac{3}{1} - \frac{6y}{1} + \frac{y}{2} \\ \frac{8y - 3 = 12 - 24y + 2y}{4} \\ 8y - 3 = 12 - 24y + 2y \\ 8y + 24y - 2y = 12 + 3 \\ 32y - 2y = 15 \\ 30y = 15 \\ y = \frac{15}{30} \: \: \: simplificar \: \: \: por \: \: \: 15 \\ y = \frac{15 \div 15}{30 \div 15} \\ y = \frac{1}{2} = 0.5$
