<h3>What is the linear system?</h3>A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.
An unknown number y is 20 more than an unknown number x.
The number y is also x less than 2.
The equations to find x and y are shown below:
y = x + 20 ...1
y = −x + 2 ...2
Add both equations, then we have
2y = 22
y = 11
Then put the value of y in equation 1, then we get
11 = x + 20
x = 11 - 20
x = -9
Then the intersection point will be (-9, 11)

<h3>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.
