Carilah hasil dari y! [tex] \frac{5}{1 - y} - \frac{7}{2 - 2y} = 4[/tex]

[tex] \frac{5}{1 - y} - \frac{7}{2 - 2y} = 4 \\ \frac{10}{2 - 2y } - \frac{7}{2 - 2y} = 4 \\ \frac{3}{2 - 2y} = 4 \\ 2 - 2y = \frac{3}{4} \\ 2y = 2 - \frac{3}{4}\\ y = 1 - \frac{3}{8} \\ y = \frac{8}{8} - \frac{3}{8} \\ y = \frac{5}{8} \\ y = 0,625 [/tex]
y = 0,625
Semoga membantu :)
