Answer :
Split it into two equations:
x - 2 = 6
and
-x + 2 = 6
-----------------------------------------------
x - 2 = 6
Add 2 to both sides:
x = 8
-x + 2 = 6
Subtract 2 to both sides:
-x = 4
Multiply -1 to both sides:
x = -4
So x = 8 and x = -4.
x - 2 = 6
and
-x + 2 = 6
-----------------------------------------------
x - 2 = 6
Add 2 to both sides:
x = 8
-x + 2 = 6
Subtract 2 to both sides:
-x = 4
Multiply -1 to both sides:
x = -4
So x = 8 and x = -4.
