p=b+3a+c p-3a-c=b+3a-3a+c-c p-3a-c=b b=p-3a-c
If a + b = 6, what is the value of 3a + 3b?
= a + b - 2
a = 15.
3a(b+c)+2b(b+c)
p=b+3a+c p-3a-c=b+3a-3a+c-c p-3a-c=b b=p-3a-c
The given expression can be simplified to: 3b-a
If a + b = 6, what is the value of 3a + 3b?
This expression can be factored. ab + 3a + b2 + 3b = a(b + 3) + b(b + 3) = (a + b)(b + 3)
3a+ax+3b+bx = 3(a+b)+(a+b)x = (a+b)(3+x)
They are terms of an algebraic expression
a number
7a-2b
a(b+3)+b(b+3)
= a + b - 2
-2a plus 3b
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
