The given expression can be simplified to: 3b-a
It is 2a-b 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
a square minus b square
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.
The given expression can be simplified to: 3b-a

2a+6b
When simplified it is: 2a+8b+4
p=b+3a+c p-3a-c=b+3a-3a+c-c p-3a-c=b b=p-3a-c
5ab-2ab+4a-b+5b = 3ab+4a+4b

If a + b = 6, what is the value of 3a + 3b?
3(a + b) + a = 3a + 3b + a = 4a + 3b
a+a+a+a+b+b - add the like terms =4a+2b 4a and 2b cannot be added because they are not like terms.
a-b+a-b+2b+a = 4a
This expression can be factored. ab + 3a + b2 + 3b = a(b + 3) + b(b + 3) = (a + b)(b + 3)
