Answer:
(3,2)
Step-by-step explanation:
Let's solve this via elimination method:

By subtracting equation 2 from equation one we obtain:

Next we can use any equation either 1 or 2 to determine what x is, I'll use equation 1. Let y=2 and so:

Therefore the solution for the system of equations is:
x=3 and y = 2 as an ordered pair we have (3,2)

Answer: 6</h3>
Mark the locations -6 and 0 on the number line. Note that going from -6 to 0, or vice versa, will take exactly 6 steps. Put another way, the distance between 0 and -6 is 6 units. Absolute value represents distance, so it is never negative.
We say 
Effectively, all we're doing is removing the negative sign.
