Question

Consider the equation 2x +4y =12. Solve for y

Answer 1

2x + 4y = 12
1/2x * 2x/1 + 4y = 12 * 2x
4y = 12 * 2x
4y/4 =12/4 * 2x
y = 3 * 2x
y = 6x

Answer 2

Hello!

Solve for y.

$2x +4y =12$

Explanation:

↓↓↓↓↓↓↓↓↓↓↓↓↓

First you had to add by -2x from both sides of the equation.

$2x+4y+-2x=12+-2x$

$4y=-2x+12$

Then divide by 4 from both sides of the equation.

$\frac{4y}{4}=\frac{-2x+12}{4}$

Simplify it should be the correct answer.

$y=\frac{-1}{2}x+3$

Answer⇒⇒⇒⇒⇒⇒y=-1/2x+3

Hope this helps!
