Answer:
5
Step-by-step explanation:
x-4=x(2)
x-4=2x
+4 +4
8 = 6
lilly has 8 stamps and mackenzie has 6
Integers are like -4,-3,-2,-1,0,1,2,3,4,5 etc
absolute value tells you how far the number is from 0
so example: |-5|=5=|5|
2 different integers can have the same absolute value
as long as they are negative of each other
like x and -x
