Răspuns :

[tex] \frac{6y + 11}{5y + 8} = 1.2(7)[/tex]

[tex] \frac{6y + 11}{5y + 8} = \frac{127 - 12}{90} [/tex]

[tex] \frac{6y + 11}{5y + 8} = \frac{115}{90} [/tex]

Simplificăm a doua fractie cu 5

[tex] \frac{6y + 11}{5y + 8} = \frac{23}{18} [/tex]

[tex]18(6y + 11) = 23(5y + 8)[/tex]

[tex]108y + 198 = 115y + 184[/tex]

[tex]198 - 184 = 115y - 108y[/tex]

[tex]14 = 7y[/tex]

[tex]y = \frac{14}{7} [/tex]

[tex]y = 2[/tex]
