Answer:
- n = (s/m) -r
- n = (s -mr)/m
Step-by-step explanation:
1. Undo the operations done to n, in reverse order. Here, n has r added and the sum is multiplied by m. First we divide by m, then we subtract r.
m(n+r) = s . . . given
n +r = s/m . . . divide by m
n = (s/m) -r . . . subtract r
__
2. Eliminate the parentheses, then proceed as above. Subtract the added term, then divide by the coefficient of n.
m(n+r) = s
mn +mr = s . . . eliminate parentheses
mn = s -mr . . . subtract the added term
n = (s -mr)/m . . . divide by the coefficient of n
