#2
-53 + n = -28
Add 53 to both sides
n = 25

OpenStudy (jessie13):
Nope they only answered #2
OpenStudy (universetoast):

x*1
OpenStudy (universetoast):
Okay, so what does anything times one equal?
OpenStudy (jessie13):

OpenStudy (universetoast):
Right! So what would x times one equal?
OpenStudy (jessie13):
