If we subtract 22 from three times a number, we get 68. Find the number.

Answer»

Let the number be x 

Then three times the number = 3x 

On subtracting 22 

⇒ 3x – 22 

By problem, 3x – 22 = 68 

3x = 68 + 22 (transposing -22) 

3x = 90 

x = 90/3 (transposing x 3) 

x = 30 

∴ The required number 30
