a is equal to 1.
it could be anything. What is a? if it is 3 then you do 4x3=12+3x3=9+3=24 * * * * * It is 8a.
4(a + 6) = 4a + 24
5ab-2ab+4a-b+5b = 3ab+4a+4b
Add the equations: 4a + 4a - 5b + 5b = 7 + 17 ie 8a = 24 a = 3, so b = 1
If your problem looks like this: 4a-a=_ the answer is... 3a
"a" plus "3a" is equal to 4a. (3a+a=4a). You already have 3 "a's" and then you add another "a."
5
4(a + 6) = 4a + 24
a is equal to 1.
If 4a+24=72 then you start out by subtracting 24 from both sides because what you do to one side of the equation you must do to the other. That means that 4a+24-24=72-24. So 4a=48. Now you divide both sides by 4 and you get a=12.
4a + 2 = 4(6) + 2 = 24 + 2 = 26
4a + 4b is one possible answer.
4*4+8 = 24
5a over 6
It is -44 + 4a
2a/3=8+4a2a=3(8+4a) 2a=24+12a -10a=24 a=-24/10 a=-12/5
