That's just combining like terms/simplifying. I am not sure if you need to find out what 'a' 'b' and 'c' are, so here's a really good site to help you. (In sources)
hi buddy this an common question in keeping with linear equations you ought to use transposition approach in this methodology while a term is transfered from one ingredient to different its sign turns into opposite answer: x+4-7x=22 =4-7x=22-x (right here x comes from the left ingredient its sign variations) =4=22-x+7x(right here 7x comes from the left ingredient its sign variations) =4-22=6x(comparable) =-18=6x x=-18/6 =-3 Bye Bye!!!!!!!!!!!!!!!!!!!!!!

Put all of the terms with "a" on the right side of the equation.
Subtract 4a f rom 9a and you get 5a:
Add 2b to both sides so it cancels on the right side
So far, it's:
5a = 2b + c
Then, divide both sides by 5
a = (2b + c)/5
Try to get all the "a" on one side of the equation.
9a - 2b = c + 4a
Add 2b to both sides:
9a = c + 4a + 2b
Subtract 4a from both sides:
5a = c + 2b
Divide by 5 to get "a" alone:
a = (c + 2b) / 5
(Note, you should write "/5" underneath the whole entire right side of the equation, because you are dividing ALL of "c + 2b" by 5.
ok so:
9a-2b=c+4a
next step, subtract the 4a
9a-4a-2b=c-4a-4a
which equals
5a-2b=c

9a-2b = c+4a
Move the a's to one side and all other stuff to the other side.
When moving variables or numbers from one side of the equation to the other side you must change the sign in front.
9a-4a = c+2b
5a = c+2b
Divide both sides by 5.
a = (c+2b)/5
9a - 2b = c + 4a
ok so first, subtract 4a from both sides:
(9a - 4a) - 2b = c + (4a - 4a)
5a - 2b = c
Then add 2b to both sides:
5a + (-2b + 2b) = c + 2b
5a = c + 2b
Then divide by 5:
a = (c + 2b)/5
1. -4a from both sides
5a-2b=c
2. +2b
5a=2b+c
3. Divide by 5
a=(2b+c)/5

a=(c+2b)/5
A = shfiffity five
what is a and what is b??????
