Answer:

x=1/2y + 2

Explanation:

multiply the equation. by -1 to make the x value positive, add -4y to both sides, not we have 8x=4y+16, now divide both sides by 8 and you get x=1/2y +2

Answer:

y=2x-4

Explanation:

well first you have to move the -8x to the other side where the -16 is. by doing so, the -8x will turn into a POSTIVE 8x. than your problem should look like (4y=8x-16). now that your problem is like that, you want "y" to be alone. so, you divide the 4 by every number. (so you would do 4y/4, 8x/4, and -16/4). than your final product would be: y=2x-4
