Question

The quotient of a number and -7, decreased by 2, is 10

Answer 1

Let the required number be x

The quotient of a number and -7, decreased by 2, is 10

According to the above problem, we get

`(x)/(( -7)) - 2 = 10 \\ (x)/(( - 7)) = 10 + 2 \\ (x)/(( - 7)) = 12 \\ x = ( - 7) * 12 \\ \boxed{x = - 84}`

Therefore, the required number is -84.

• -84 is the right answer.
