Yes. Say 1 of those terms is "x". The other 99 terms are called parameters and they can be whatever number you want. X would be the dependent variable or something like that. You would have an infinite amount of solutions to the equation.

move the one term onto one side by itself. You do this by adding or subtracting the same quantity from both sides. If you have a + x + b = c + 4x + d subtract c and d from both sides: a + x + b - c - d = 4x subtract x from both sides: a + b - c - d = 3x Now divide to get x by itself: (a + b - c - d)/3 = x It is now the subject. The equation acts like a two-pan balance. Adding and subtracting the same amount from both sides doesn't affect the balance.
