Question

.ajutor imi trebuie urgent ​

Answer 1

$\frac{6y + 11}{5y + 8} = 1.2(7)$

$\frac{6y + 11}{5y + 8} = \frac{127 - 12}{90}$

$\frac{6y + 11}{5y + 8} = \frac{115}{90}$

Simplificăm a doua fractie cu 5

$\frac{6y + 11}{5y + 8} = \frac{23}{18}$

$18(6y + 11) = 23(5y + 8)$

$108y + 198 = 115y + 184$

$198 - 184 = 115y - 108y$

$14 = 7y$

$y = \frac{14}{7}$

$y = 2$
