A=5How to do it:30=6aa=6/6 (Do on both sides) 30/6a=(6/6 cancels out) 30/6a=5
If 6a divided by 2 equals 12 then A equals
6a + (7b - 4a - 8b) = (6a - 4a) + (7b - 8b) = 2a - b
6a-3=8a+11 -3-11=8a-6a -14=2a a=-7
Well, honey, if you've got 6 of something and you take away 10 of the same something, you're gonna end up with a negative number, specifically -4 of that something. So, 6a - 10a equals -4a, not 16. Math can be a real tricky little devil sometimes, can't it?
