Question 944698: Andrew is trying to create a number puzzle for his younger sister to solve. He challenges his sister to find the mystery number. "When 4 is subtracted from half of a number the result is 5." His sister says the number is 4 1/2. Is she correct? Explain why or why not?

The number is X
1/2X -4 = 5
1/2X = 5+4
1/2X = 9
X = 18
So his sister is incorrect.
