a = -2-4a/3-2 = 8-4a = 8(3-2) times both sides by (3-2)-4a = 24-16-4a = 8-a = 2 divide both sides by 4a = -2 times both sides by -1
A = 7. 4a + 3 - a = 24 4a - a = 21 3a = 21 a = 7
2a*3 = 8+4a 6a = 8+4a 6a-4a = 8 2a = 8 a = 4
12a.
"a" plus "3a" is equal to 4a. (3a+a=4a). You already have 3 "a's" and then you add another "a."
no
3 over forty
It depends on the exact form. If it is 4a + 12/(a + 3) then a cannot be -3 However, (4a + 12)/(a + 3) simplifies to 4. So there is no variable to worry about!
2 2/3
(24 times 3) + (6 over 2) = 75
9/8 ("9 over 8")
6
