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.

<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.

$\underline{\text{DISTRIBUTIVE PROPERTY:}}$

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.
