Pick any formula, choose which variable to isolate, and get the rearranged equation with full algebraic step-by-step work. Enter known values to compute a numeric answer too.
A = l × w → l = A ÷ w
A literal equation is any equation that contains two or more variables (letters). Most formulas in math and science are literal equations.
To solve for a variable, apply inverse operations to isolate it on one side — the same moves you use with numbers, but you're manipulating letters instead.
Key inverse operations: addition ↔ subtraction, multiplication ↔ division, squaring ↔ square root.
The same formula is used in many different situations. You might know the area but not the length, or know the voltage but not the resistance. Rearranging lets you solve any version of the same problem.
