Final answer:
To isolate y in the equation 4y + 4x = 12, divide by 4 to get y + x = 3, and then subtract x from both sides to get y = 3 - x.
Step-by-step explanation:
To express y in terms of x from the given equation 4y + 4x = 12, you'll need to isolate y. Begin by simplifying the equation:
- Divide each term by 4 to simplify the equation to y + x = 3.
- Now, subtract x from both sides to get y = 3 - x.
So, in terms of x, y is equal to 3 - x.
This is a linear equation where the variable x is the independent variable and y is the dependent variable.
