Question

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

Answer 1

Answer:

$y=-2x+3$

Step-by-step 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:

$y=-2x+3$
