Answer 6

To make y the subject of the formula, you divide 2 to 4 on the other side of the equal sign. So you are left with x-y on the left side of the equation. So to make y in x-y, you take x on the right side of the equal sign so it will be 2 + x. So to make y positive, you divide 2+x by -1 so your final answer will be, 2+x/-1
