Seven less than the quotient of a number, x, and twelve is five times the number

x = -1.42

Step-by-step explanation:

The quotient of a number x and twelve would be: x/12.

But the problem tells us that seven less than this quotient is 5 times the number. Written as an equation and solving for x this would be:

Therefore x = -1.42
