Question

Solve for the indicated variable.
8x + 4y = 12; y
​

Answer 1

`y=-2x+3`

Explanation:

Given:
`8x+4y=12`

To solve for y, let us first isolate y on one side of the equation. We can do this by subtracting
`8x` from the left and move it to the right. We then get:

`4y=12-8x`

Now, we have y isolated. We now have to remove the 4 from the y. The only way to do this is divide both sides by 4. We then get our final answer:

`y=3-2x`

We can clean this up by putting it in a common form, slope-intercept form:

`y=-2x+3`
