Question

Alguém que saiba responder essa daqui:
2y/9+1/6=4y/3+1/2 ???

Answer 1

$\frac{2y}{9} + \frac{1}{6} = \frac{4y}{3} + \frac{1}{2}$

mmc (9,6,3,2)

9, 6, 3, 2  | 2
9, 3, 3, 1  | 3
3, 1, 1, 1  | 3
1, 1, 1, 1  |

2 * 3 * 3 = 6 * 3 = 18

$\frac{4y}{18} + \frac{3}{18} = \frac{24y}{18} + \frac{9}{18}$

denominadores iguais cancela

4y + 3 = 24y + 9
4y - 24y = 9 - 3
-20y = 6 (-1)
20y = - 6

$y = - \frac{6}{20} = -\frac{3}{10}$
