Answer:
[tex] \frac{7y}{10} + 2 = \frac{5y}{6 } [/tex]
[tex]30 \times \frac{7y}{10} + 2 \times 30 = 30 \times \frac{5y}{6} [/tex]
[tex]3 \times 7y + 60 = 5 \times 5y[/tex]
[tex]21y + 60 = 25y[/tex]
[tex]21y - 25y = - 60[/tex]
[tex] - 4y = - 60[/tex]
[tex]y = \frac{ - 60}{ - 4} = \frac{60}{4} = 15[/tex]
