I really, really need help!
Solve for the indicated variable.
8x+4y=12
Solve for y.
Explanation too, please!
Please and thanks!
8x+4y=12
4y = 12 - 8x
y = (12 - 8x)/4
y = 3 - 2x
Thank you! (:
You're welcome.
To solve for y in the equation 8x + 4y = 12, you need to isolate the variable y on one side of the equation. Here's how you can do it:
Step 1: Start with the given equation: 8x + 4y = 12.
Step 2: Subtract 8x from both sides of the equation to get the term with y alone on one side. The equation becomes 4y = 12 - 8x.
Step 3: Now, to isolate y, divide both sides of the equation by 4. This gives you y = (12 - 8x) / 4.
So the solution to the equation when solving for y is y = (12 - 8x) / 4.
This means that the value of y can be determined by substituting the value of x into the expression (12 - 8x) / 4.
