You can't just solve one side of the equation. You always have to have both sides of the equal sign in order to manipulate the terms.
If you have an equation like 10a + 5b=0, you can now solve for one of the terms (a or b), for example, b=10a/5 and a=-5b/10. Once you have solved for one term, you can plug it back into the equation and solve for real values.
In this particular equation, a=-1/2b so by putting any value in for b (say 2), you get a definite value for a (-1) but there are an infinite number of such values.

What is 7a plus 2b plus 3a plus 5b equal?
10a+7b undefined variables cannot be determined
2(a plus b) plus 3(a plus b) plus 5a?
10a + 5b
10a-5b equals 25 what is b?
10a - 5b = 25 So 5b = 10a - 25 and hence b = 2a - 5
Subtract the sum of 10a and 5b from the product of 4and 3f?
The expression is simplified to: 12f-(10a+5b)
How do you factor 10a 5b?
The only common factor of 10a and 5b is a 5. So the factored form will be something like: 5(2a _ b) assuming the _ is filled in with the proper operation (+ - * / etc.). If the original expression is 10a + 5b, the answer would be 5(2a + b).
How do you solve 5b plus 3 equals 10?
5b + 3 = 10 - 3 - 3 5b = 7 5b/5 7/5 b= 1.5 There you go !
How do you simplify 10a-4parentheis A plus 2 parentheis?
to solve this expression: 10a-4(a+2) -> 10a-4(a)-4(2) -> 10a-4a-8 -> 6a-8
