Question

ranslate the following sentence to an equation. Then solve the equation. 50 subtracted from four times a number is 1 more than the number. Find the number.

Answer 1

17

Explanation:

Let the unknown number be n. Then,

"50 subtracted from four times a number is 1 more than the number"

translates into the equation 4n - 50 = n + 1.

Solve this by subtracting n from both sides: 3n - 50 = 1,

continuing by adding 50 to both sides: 3n = 51.

Dividing both sides by 3 yields n = 17.

The number is 17.
