-15r=-75
%28-15r%2F-15%29=%28-75%2F-15%29 [isolate the x-term]
x=5
.
Check by plugging (x=5) back into the original equation and solve:
-15r=-75
-15(5)=-75
-75=-75 [checks out]
.
x-(-16)=44
x+16=44 [simplify as much as possible]
x+16-16=44-16 [isolate the x-term]
x=28
.
Check by plugging (x=28) back into the original equation and solve:
x+16=44
28+16=44
44=44 [checks out]
