5a + 4b - 3a =(5a - 3a) + 4b =2a + 4b =2 (a + 2b)

2a + 4b

Change the order to make it more obvious: 3a - a + 2b + 4b 2a + 6b or 2 (a + 3b).

7ab

Clearly, there are some signs missing. So let's try the four possibilities for the second terms: 1. + and + 3a + 4b = 7a + 4b Subtract 4b from each side: 3a = 7a Subtract 3a from each side: 0 = 4a Answer : a = 0, b indeterminate (ie can have any vaue). 2. + and - 3a + 4b = 7a - 4b Subtract 4b from each side: 3a = 7a - 8b Subtract 7a from each side: -4a = -8b or 4a = 8b Answer: a = 2b 3. - and - 3a - 4b = 7a - 4b Add 4b to each side: 3a = 7a Subtract 3a from each side: 0 = 4a Answer : a = 0, b indeterminate (ie can have any vaue). 4. - and + 3a - 4b = 7a + 4b Add 4b to each side: 3a = 7a + 8b Subtract 7a from each side: -4a = 8b or 4a = -8b Answer: a = -2b Can't do better than that with the information available.

6b+5a-4b+3a= ? Rearrange it as 5a+3a+6b-4b = 8a+2b

3a + 4b - (-6a) - 3b? There is no equivalent because you did not make it an equality. However you could combine the numbers... 3a + 4b +6a -3b = 9a + 1b

It is: 3a(1-4b)

5 x 3a= 15a

3a + 5b - 6a - 9b = -3a - 4b

Your GPA would be 3.42

2a + 4b - 52a + 4b - 52a + 4b - 52a + 4b - 5

a x a x a = a3

3A + 9B = 3(A + 3B)

Add them together: 3a+4a-a = 6a

81(a^4)

It is an algabraic expession without knowing whether or not 2b and 3a are plus or minus

Numerically, if the question looks like this:--(3a + 7b) - 8a - 4b + 2Then the answer is this:--3a - 7b - 8a - 4b + 2= -11a -11b + 2

2a x 3b = 6ab

1a+3b 2a+4b=3a +7b

You can take (x - 2y) out of all three of those terms, leaving 3a, 4b and c.

2a(3a - 4b + 1)

a + 3a - 2 + 3a. Add the a + 3a + 3a = 7a. You can't combine the -2 & 7a so the solution is: 7a - 2.
