Question

One number is six times as large as a certain smaller number. Let x represent the smaller number.

Write the number that is 20 more than the smaller number.

Answer 1

24

Explanation:

6x = x + 20

Subtract x from both sides

5x = 20

Divide by 5 on both sides

x = 4

Confirm

4 times 6 equals 24, and 4 + 20 is 24 as well.

Answer 2

4x=20
divide 4 on both sides
