"a" plus "3a" is equal to 4a. (3a+a=4a). You already have 3 "a's" and then you add another "a."
4a
7a-2b
It is: 7a+1 when simplified
4a+2b-1a+9b combine all alike variables using commutative property of addition 4a-1a+2b+9b Then add the like variables 3a+11b
4a+3-a =12 4a-a = 12-3 3a = 9 a = 3
5ab-2ab+4a-b+5b = 3ab+4a+4b
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!
4a
5
a=-12
8a+4a=144 12a=144 12a/12=144/12 A=144
The question contains neither an expression nor an equation (or inequality). There can, therefore be no sensible answer.
The Answer is 4a so you are asking why it is 4a. So just take an a and think it as 1a boom
It is -44 + 4a
a < -12
2 x (2a + 3b - 6)
