Question

Six times a number is greater than 20 more than that number what are the possible values of that number

Answer 1

Let n = the unknown number.

Six times a number = 6 * n = 6n

20 more than number = n + 20

Greater than = >

Put it all together:

6n > n + 20

Subtract n from both sides to get constants on one side and variables on the other:

6n - n > 20

5n > 20

Divide both sides by 5 to isolate variable N

n > 4

or (4, ∞)
