Answer:

[tex]\boxed{y=2}[/tex]

Step-by-step explanation:

[tex]6(y + 5) = 15y + 12[/tex]

[tex]\sf Expand \ brackets.[/tex]

[tex]6y+30=15y+12[/tex]

[tex]\sf Subtract \ 12 \ and \ 6y \ from \ both \ sides.[/tex]

[tex]6y+30-12-6y=15y+12-12-6y[/tex]

[tex]30-12=15y-6y[/tex]

[tex]18=9y[/tex]

[tex]\sf Divide \ both \ sides \ by \ 9.[/tex]

[tex]\displaystyle \frac{18}{9} =\frac{9y}{9}[/tex]

[tex]2=y[/tex]

6y+30=15y+12
9y=18
y=2
