Question

If you reduce a twelve times a number by 40, you get the same number as if you increase its seven times by 25. What number is that?

Answer 1

Step-by-step explanation:

Take the number as x

12x-40=7x+25

collect like terms

12x-7x=25+40

5x=65(divide both sides by 5)

x=13

Therefore number is 13
