\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.
