The quotient of a number and -7,<br> decreased by 2, is 10. Find the<br> number.

garik1379 [7]

Answer:

-84

Step-by-step explanation:

Let the number be x. Then we have,

$\frac{x}{-7}$ (the quotient of a number and -7)

$\frac{x}{-7}-2$ (decreased by 2)

$\frac{x}{-7}-2=10$ (is 10)

Now we can solve for x,:

$\frac{x}{-7}-2=10$

$\frac{x}{-7}=12$

$x=-84$

So, the original number is -84
