Question

If 21 less than 11 times a number results in 7 times a number decreased by 29, what is the number?

Answer 1

Hi Micaela V.

Let n represent your unknown

According to the information given

11n - 21 = 7n -29

Move the variables to one side of the equation and the constants to the other by adding their opposites

11n - 7n = 21 - 29

4n = -8

Now just solve for n

Check your result by plugging n into both your original equations
