by using your brain
Scientists will generally use their brains to solve math or other problems. Once they have established the mathematical formula to be solved, they would use a computer or (scientific) calculator to evaluate the math problem and get a solution.
The question contains an expression, not an equation nor inequality. An expression cannot have a solution.
These questions are meant to be used as a school-wide exercise. Your teacher should explain the solution after everyone has had a chance to solve it.
Solvable is an adjective related to the word solve. For instance, The math problem was not solvable to the students, as they did not have enough calculus instruction.
common logarithms, natural logarithms, monatary calculations, etc.
If my math works, the solution if you are solving for b is (2a-ba)÷(-b)=b.

answer
IF they are math related, write appropriate equations and then apply math rules to solve the equations.
If you need explanations for things then the best math site is purple math. If you want a site that will solve your homework and you just have to put the problem in it will be mathway. But on mathway the answers are provided but you have to pay to see the step by step solution.
