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

(06.01) In the below system, solve for y in the first equation. x + 3y = 6 2x − y = 10 one thirdx + 2 negative one thirdx + 6 −x

NISA [10]

we have that

x + 3y = 6 -------> first equation

2x − y = 10

x + 3y = 6-----> substract x both sides

-x+x+3y=6-x

3y=6-x-----> divide by 3 both sides

y=(6-x) /3

y=2-(x/3)

y=-(x/3)+2

therefore

the answer is

negative one thirdx + 2
