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

-2a plus 3b

1

The given expression can be simplified to: 3b-a

The idea here is to combine terms that have the same variable (or, in more complicated cases, the same combination of variables). For example, 3a + 2a is the same as 5a.

Gathering like terms together, this is equal to 5a + 3b + 7c.

-2

It is: 2a+5a = 7a when simplified

a + b + c = 180 b = 3a c = 5a Substituting the values of b and c into the first equation. a + 3a + 5a = 180 or 9a = 180 so that a = 20 then b = 3a = 3*20 = 60 and c = 5a = 5*20 = 100

2a-6a-a=b+4b-4b -5a=5b-4b -5a=1b a=-5 b=1

= a + b - 2

From your description, I get: a + b + c = 180b - 3a c = 5a You have two equations and three unknowns, which is unsolvable.

2a+2b+3a+3b+a+b= 6a+6b 2a+3a+a=6a 2b+3b+b=6b

2a

3a + 4b - 5 - 1a + 7b + 3 - 1b 2a + 10b - 5 + 3 2a + 10b - 2

When simplified it is: 2a+8b+4

a = 20 b = 60 c = 100

a + b - 2 is the answer in simplest terms. without telling us what a or b is this is the most accurate answer.

(2a - 5b)(5a - b)

12a + 6b + 6c = 6(2a + b + c)

p=b+3a+c p-3a-c=b+3a-3a+c-c p-3a-c=b b=p-3a-c

2a2b2+3a2b2-5abc

6a²b - 12ab²

2a+b=2a+b. Without a value for a and b, the expression has no value.

2a-3+4b-2a-b-2a-b-3+5 Can be simplified to: 3b-1
