By adding 3 to both sides
-5m + 7n = p +3
By adding 5m to both sides
7n =p + 3 + 5m
By dividing both sides by 7
[tex]n = \frac{p+3 + 5m}{7} [/tex]
-5m + 7n = p +3
By adding 5m to both sides
7n =p + 3 + 5m
By dividing both sides by 7
[tex]n = \frac{p+3 + 5m}{7} [/tex]
p = -5m + 7n - 3
Add 5m to both sides:-
p + 5m = 7n - 3
Add 3 to both sides:-
p + 5m + 3 = 7n
Finally divide both sides by 7:-
(p + 5m + 3)/ 7 = n answer
