They are equivalent because they are showing the Distributive Property....The Distributive Property shows that you can Distribute one number into another one, and still get the same answer.....So, you would have to do 4x+4y!!! I hope this helps!!!
Three fourths is the same thing as six eighths so first draw three fourths of a pie shade three out of four next make it into seighths now you have six shaded in!!!(hope this helps!!!;)
