Half a number is 18 more than 5 times the number. Find the number

Question

You have to solve this question with an equation

Answer 1

number = x

 

Half a number=(1/2)x

 

5 times the number=5x

 

Half a number is 18 more than 5 times the number

 

(1/2)x=5x+18

 

subtract 5x from both sides

 

(1/2)x -5x = 18

 

-4.5x =18

 

x = -4

 

number = x=-4

Answer 2

Let the number be X. Then this word problem reads as such:

Half a number:  (0.5*X)
is: (=)
18 more than: (18 +)
5 times the number: (5*X). 

Or:

0.5*X = 18 + 5*X

Let us solve this for X.

-4.5*X = 18
X = -4
