If I have an equation like 6+3y-4 can i move the 3y to the back to deal with the 6 and the -4? ex: 6-4+3y?

Yes as long as you keep the sign in front of it

U ok yeah u go do that

I'll do the first one for you. it isn't very hard at all.on number one, you have (50 × 3), which equals 150, and (3 × 3), which equals 9. after you establish that, you add 150 and 9 together. so, (150 + 9) equals 159.this means that 53 × 3 = 159.
