$\huge \boxed{\mathbb{QUESTION} \downarrow}$

What is $\tt\:y+3y=0+24$ ? Explain it.

$\large \boxed{\mathbb{ANSWER\: WITH\: EXPLANATION} \downarrow}$

$\tt \: y + 3 y = 0 + 24$

Combine y and 3y to get 4y.

$\tt \: 4y=0+24$

Add 0 and 24 to get 24.

$\tt \: 4y=24$

Divide both sides by 4.

$\tt \: y=\frac{24}{4} \\$

Divide 24 by 4 to get 6.

$\boxed { \boxed {\bf \: y=6 }}$
