Question

John's age increased by 11 is 5 less than 5 times his age. How old is he?

If x represents John's age, which of the following equations could be used to solve this problem?
Ox+11 - 5 = 5x
x + 11 = 5x -5
x + 11 = 5 - 5x

Answer 1

x+11 = 5x - 5

Explanation:

x+ 11 = 5 x − 5

Subtract x from both sides

11 = 4 x− 5

Add 5 to both sides

16 = 4 x

Divide both sides by 4

x=4
