Question

What is the answer to 10n=40

Answer 1

Solving for variables is easy as all we must do is isolate the variable and simplify. In this case, to isolate the variable, we simply need to divide "n" by 10 (because the "n" is being multiplied by 10).

 10n=40
/10   /10
n=4

Using the math above, we can see that n=4.
