Answer:

The value of y is 7.

Step-by-step explanation:

The given equation is

[tex]log_{11}(y+8)+log_{11}4=log_{11}60[/tex]

[tex]log_{11}[(y+8)4]=log_{11}60[/tex]               [tex][\because log_ax+log_ay=log_axy][/tex]

[tex]log_{11}(4y+32)=log_{11}60[/tex]

Equating both sides.

[tex]4y+32=60[/tex]

[tex]4y=60-32[/tex]

[tex]4y=28[/tex]

Divide both sides by 4.

[tex]y=7[/tex]

Therefore the value of y is 7.
