Answer:

The number is -3.

Step-by-step explanation:

Set up an equation:

Variable n = number

12 + 7n = n - 6

Assuming the question is solve for n, isolate the variable:

Subtract n from both sides:

12 + 6n = -6

Subtract 12 from both sides:

6n = -18

Divide by 6 on both sides:

n = -3

Check your work:

12 + 7(-3) = -3 - 6

12 - 21 = -3 - 6

-9 = -9

Correct

$\qquad\qquad\displaystyle \huge Answer$

Let's check if (3 , 6) is the point of intersection of the given lines ~

$\qquad \displaystyle \: y = 4x - 2$

and

$\qquad \displaystyle \: y = \frac{1}{2} x + 5$

If the point is the point of intersection of these two lines, then it should satisfy both the equations ~

let's try each of them, using x coordinate of point.

$\qquad \displaystyle \: y = 4(3) - 2$

$\qquad \displaystyle \: y = 12 - 2$

$\qquad \displaystyle \: y = 10$

So, the point didn't actually satisfy one of the equation. hence we can infer that the given statement is wrong.
