Question

10 subtracted from half of a numbee gives 15
What is the number ?

​

Answer 1

Answer:

x = 50

Step-by-step explanation:

The problem would be set up like this:

x(1/2) - 10 = 15

You need to get rid of -10, so you do the opposite (add it to both sides).

15 + 10 = 25, the problem then changes to this:

x(1/2) = 25

Since x is being multiplied by 1/2, you do the opposite to the other side, which will be multiplying 2.

x = 25(2)

x = 50

Plug in 50 for x to check your answer. :)
