a+1+x+m=80
Add -4 and 5 to get 1.
a+x+m=80-1
Subtract 1 from both sides.
a+x+m=79
Subtract 1 from 80 to get 79.
a+m=79-x
Subtract x from both sides.
a=79-x-m
Subtract m from both sides.
a+1+x+m=80
Add -4 and 5 to get 1.
1+x+m=80-a
Subtract a from both sides.
x+m=80-a-1
Subtract 1 from both sides.
x+m=79-a
Subtract 1 from 80 to get 79.
m=79-a-x
Subtract x from both sides.
