Twice a number is 60 more than 5 times the number. What is the number?

Question

Write an equation to find each number. Then solve.

Answer 1

Twice a number:  2x

is 60 more than:  = 60 +

5 times the number:  5x

 

Putting this together:

2x = 60 + 5x

 

subtract 5x from both sides

 

-3x = 60

 

divide both sides by -3

 

x = 60/(-3)

x = -20
