Turn a “find the number” word problem into an equation and solve it. Pick the phrasing, enter the numbers, and this word problem solver builds the linear equation and works through every step — like 10 added to four times a number is 46.
The three boxes fill the blanks left to right. Switch the phrasing above to change what the words between them say.
Step by step
The trick to every “find the number” problem is translating the words into algebra, one phrase at a time.
Let the number you’re looking for be x. Every “a number” in the sentence becomes that same x.
“Four times a number” is 4x, “10 added to” means + 10, and “is” (or “the result is”) becomes =. So 10 added to four times a number is 46 becomes 4x + 10 = 46.
Peel the equation back in reverse: subtract 10 (4x = 36), then divide by 4 (x = 9). The solver shows each step and checks the answer. Solving two unknowns instead? Use the System of Equations Solver; for ax²+bx+c=0 see the Quadratic Formula Calculator.
