Frequently Asked Questions
How do I solve an equation with unknowns on both sides?
Move all the terms with the unknown to one side and all the number terms to the other. E.g. 5x + 3 = 2x + 12 โ 3x = 9 โ x = 3.
How do I solve an equation with fractions?
Multiply every term in the equation by the denominator (or LCD if there are multiple fractions) to clear the fractions, then solve normally.
