X + y = 12
x - y = 4
From the second equation we can see that x = 4 + y
We can plug this into the first one and get:
4 + y + y = 12
4 + 2y = 12
2y = 12-4
2y = 8
y = 4
And then we can plug that into “x” and get that x = 4 + 4, or x=8
No the points have to be on a cross on the x and y axis
The absolute value of a number is how many digits away from zero it is, the actual value includes negative numbers while absolute value numbers do not include negatives

Answer:
y = 18
Step-by-step explanation:
The angles 8y - 102 and 2y + 6 are vertical and congruent, thus
8y - 102 = 2y + 6 ( subtract 2y from both sides )
6y - 102 = 6 ( add 102 to both sides )
6y = 108 ( divide both sides by 6 )
y = 18
