3a is part of an algebra equation. It mean the variable "a" time 3. to solve, you need to know the value of a. if the value of a is 5 the 3a would be 3 x 5 which is 15.
3a + 4 = 4a - 3 4 = a -3 (subtract 3a from each side) 7 = a (add 3 to both sides) a = 7
depends what 'a' =
36 -20 = 16
What is the answers to -7 ( a + b - 5 ) + 8 ( -3a +2b ) + b ( 7 + 3 )
3a + 2b = c (find a in terms of b and c)3a +2b -2b = c - 2b3a = c - 2b3a/3 = (c - 2b)/3a = (c - 2b)/3In order to find the value of a, you can give any values to b, and c (except a zero value).
You don't have a number alone. Also I'll make the assumption that it is 19a+2a-4a+3a Without a number alone, it can't really be solved, unless a=0 19a+2a-4a+3a can be simplified however to 20a
Pressumably you want to solve for "a". Divide both sides of the inequality by 3. That will give you the solution.
