Question

If you add (-7) to a number, you will get 100. Find the number​

Answer 1

107

Explanation:

If we add -7 to a number, that number will be 107.

• 107 + (-7) = 100

Let x represent the unknown number.

• x + (-7) = 100
• x - 7 = 100

Let's add 7 to each side:

• x - 7 + 7 = 100 + 7

• x = 107

Therefore, if you add -7 to 107 you will get 100.
