The Answer is 4a so you are asking why it is 4a. So just take an a and think it as 1a boom
6-3a**2+7+4a-5a+18 3a**2-1a+31
4a+5=25 4a=25-5 4a=20 a=20/4 a=5
4a + a = 25 add 4a and a 5a = 25 then divide 25 by 5 a = 5
4a-13 = 19 Add 13 to both sides: 4a = 32 Divide both sides by 4 to find the value of a: a = 8
2a + 9 = 4a - 19 9 + 19 = 4a - 2a 28 = 2a a = 14
A = 6
4a+2b-1a+9b combine all alike variables using commutative property of addition 4a-1a+2b+9b Then add the like variables 3a+11b

-1
It can do, for the right value of A
10
4a+3-a =12 4a-a = 12-3 3a = 9 a = 3
4a+5=25 4a=25-5 4a=20 a=20/4 a=5
