Question

Twenty-five subtracted from ½ a number is 10. What is the number?

Answer 1

Answer:

The number is 30.

Step-by-step explanation:

The number = x

25 - 1/2(x) = 10

Mutliply both sides by 2, because you does not want the fraction

50 - x = 20

Now, you have no more fraction. Just move 50 to the right side and change its sign

-x = 20-50

-x = -30

Change its sign

x = 30

So, the number is 30.
