The answer ... usually called the "solution" ... is the number that 'a' must be
in order for the statement to be true. There's only one such number.
You said that [ 1 - 4a = 21 ].
I would begin by adding ' 4a ' to each side of the equation:
1 = 21 + 4a
Now subtract 21 from each side:
-20 = 4a
Finally, divide each side by 4 :
-5 = a
7...that is the LCM or least common multiple Because 7X2a=14a and 7X3=21
70a
12a
To factorize 14a + 21, you first need to find the greatest common factor of the two terms, which in this case is 7. You can factor out 7 from both terms to get 7(2a + 3). Therefore, the factorized form of 14a + 21 is 7(2a + 3).
negative 1
a(-14-a) = 0 so a = 0 or a = -14
a=5 (14 x 5 = 70 ; 35 - 70 = -35)
I'm assuming you mean: 14a - 93 = 49 - 57a If so then the answer is something like this... 14a + 57a = 49 + 93 which is... -> 71a = 142 which makes a = 142/71 = 2 so : a = 2 Hope that's what you were looking for! Your welcome if it was! :)
21 equals dots on a dice
28*21 equals 84
21
5q-29 equals 21 5q equals 50 q = 5
