Answer:
Two points, one at 4 and one at 6.
Step-by-step explanation:
<u>Equations with absolute value
</u>
The absolute value of a number x denoted as |x| is a number with the same magnitude with a positive sign. When we know the result of an absolute value, we cannot know if the original number is positive or negative.
If |x| = a, a>=0, then x=a or x=-a
The equation to solve is |x – 5| = 1. If we apply the above criteria, then
x-5=1 or x-5=-1
Which gives us two possible solutions for x
x=6
x=4
The correct answer is
Two points, one at 4 and one at 6.

Answer:x = - 5
y = 2
Step-by-step explanation:
The given system of simultaneous equations is expressed as
x + 3y = 1 - - - - - - - - - - - - - -1
4x + 4y = -12 - - - - - - - - - - - 2
We want to eliminate x. Multiplying equation 1 by 4 and equation 2 by 1, it becomes
4x + 12y = 4
4x + 4y = - 12
Subtracting the second equation from the first equation, it becomes
8y = 16
y = 16/8 = 2
Substituting y = 2 into equation 1, it becomes
x + 3 × 2 = 1
x + 6 = 1
x = 1 - 6 = - 5
