For m + 10, the table can be formed as follows:












































m



m + 10



1



1 + 10 = 11



2



2 + 10 = 12



3



3 + 10 = 13



4



4 + 10 = 14



5



5 + 10 = 15



6



6 + 10 = 16



7



7 + 10 = 17



8



8 + 10 = 18



9



9 + 10 = 19



From the above solution, we find that:


m = 6 is the solution of the given equation as


m + 10 = 6 + 10


= 16

(a) 5m = 60 (10, 5, 12, 15)


(b) n + 12 = 20 (12, 8, 20, 0)


(c) p – 5 = 5 (0, 10, 5, -5)


(d) =7 (7, 2, 10, 14)


(e) r - 4 = 0 (4, -4, 8, 0)


(f) x + 4 = 2 (-2, 0, 2, 4)
