It's fine. I tried to see if my friend, he's a Junior in the same class as me, understood it. And he was more lost than me
-
emarsh1999 NewbieSo...
((x-4)3)-1=8.3
3x-12-1=8.3. -distributive property
3x-11=8.3.
3x-11+11=8.3+11. -additive property of equality?
3x=19.3
x=19.3/3 -
emarsh1999 NewbieYou have to think out how the problem will work, then lime the lesser being 4 is just plugging in 4 where x or y would go. 4 is y too because it is a part of the original difference in number 1
-
Which problem was that?
-
emarsh1999 NewbieOh and the 19.3/3 step is dividing both sides by 3, another property of equality
-
Oh. I understand it a bit better now. I kept thinking a completely different way. face palm
