7A + 3
(a2 + 5a + 6)/(a - 2) = (a + 2)*(a 3)/(a - 2) which cannot be simplified further. It can, however be written as (a2 - 2a + 7a - 14 + 20)/(a - 2) which is (a + 7) + 20/(a - 2)
3a + 4a +/- 6; take the 3a & 4a and combine them; 7a +/- 6 would be your answer as 6 cannot combine with 7a due to the variable. If 7a +/- 6 = 0, then subtract/add (respectively) the 6 depending on the operation. Therefore 7a + 6 = 0 turns to 7a = -6. Divide the 7 with the -6 to get the a alone; a = -6/7 or -0.8. Cannot be simplified.
10a+7b undefined variables cannot be determined
a + 18 = 7a a-a +18 = 7a-a 18 = 6a 18/6 = 6a/6 3 = a 3=a
7a
It is: 2a+5a = 7a when simplified
7A + 3
It is: 7a+1 when simplified
(a2 + 5a + 6)/(a - 2) = (a + 2)*(a 3)/(a - 2) which cannot be simplified further. It can, however be written as (a2 - 2a + 7a - 14 + 20)/(a - 2) which is (a + 7) + 20/(a - 2)
Oh, dude, it's like math time! So, when you add 3a and 7a together, you get 10a. It's like combining the apples and oranges of algebra. So, the simplified answer is just 10a. Easy peasy, lemon squeezy!
3a+5b+7a=
It can be simplified to: -45a-15
You need to combine the different parts that contain the variable "a". Just add the coefficients together algebraically.
-7a + 3a = -4a
(7a=3)=(-a-5)=16
9a-a = 19+7a 8a = 19+7a 8a - 7a = 19 + 7a - 7a 1a = 19 a = 19
