To solve for y, let us first isolate y on one side of the equation. We can do this by subtracting from the left and move it to the right. We then get:
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:
We can clean this up by putting it in a common form, slope-intercept form:
