3a + 2b is an expression in algebra. If you make 3a + 2b equal to something then you can find the values of "a" and "b"
Lets say you make 3a + 2b equal to 23
3a + 2b = 23
Now find "a" and "b" to make this equation true...
3(5) + 2(4) = 23
15 + 8 = 23
23 = 23 Correct
So in this case a=5 and b=4

Solve for the variable specified. Assume domains include only values that give nonzero denominators.3a plus 2b equals c for a?
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).
