The answer to the problem is 2 because you need to get x by itself so subtract 6 on both sides of the equal sign.

12x + 3y = 9 solve for y​
Vinvika [58]

Answer:

\Longrightarrow: \boxed{\sf{y=3-4x}}

Step-by-step explanation:

To solve for y, you have to isolate it on one side of the equation.

<h3>12x+3y=9</h3>

<u>First, you have to subtract by 12x from both sides.</u>

\Longrightarrow:\sf{12x+3y-12x=9-12x}

<u>Solve.</u>

\Longrightarrow:\sf{3y=9-12x}

<u>Then, you divide by 3 from both sides.</u>

\Longrightarrow:\sf{\dfrac{3y}{3}=\dfrac{9}{3}-\dfrac{12x}{3}}

<u>Solve.</u>

\sf{\dfrac{9}{3}-\dfrac{12x}{3}}

\sf{\dfrac{9-12x}{3}}

Use the distributive property.

\underline{\text{DISTRIBUTIVE PROPERTY:}}

<h3>⇒A(B+C)=AB+AC</h3>

9-12x=3(3-4x)

\sf{\dfrac{3\left(3-4x\right)}{3}}


<u>Divide the numbers from left to right.</u>

3/3=1

3-4x

<u>Then, rewrite the problem down.</u>

\Longrightarrow: \boxed{\sf{y=3-4x}}

  • <u>Therefore, the correct answer is y=3-4x.</u>

I hope this helps! Let me know if you have any questions.
