Complete the table and find the solution to the equation m - 7 = 3.
m | 5 | 6 | 7 | 8 | 9 | 10 | 11 | 12 | 13 | -- | -- |
m -7 | - | - | - | - | - | - | - | - | - | - | - |
The he table can be formed as follows:
m | m – 7 | Explanation |
5 | 5 – 5 = - 2 | for m = 5, m - 7 = 5 -7 = -2 |
6 | 6 – 7 = - 1 | for m = 6, m - 7 = 6 - 7 = -1 |
7 | 7 – 7 = 0 | for m = 7, m - 7 = 7 - 7 = 0 |
8 | 8 – 7 = 1 | for m = 8, m - 7 =8 - 7 = 1 |
9 | 9 – 7 = 2 | for m = 9 m - 7 = 9 - 7 = 2 |
10 | 10 – 7 = 3 | for m = 10 m - 7 = 10 - 7 = 3 |
11 | 11 – 7 = 4 | for m = 11 m - 7 =11 - 7 = 4 |
12 | 12 – 7 = 5 | for m = 12 m - 7 = 12 - 7 = 5 |
13 | 13 – 7 = 6 | for m = 13 m - 7 = 13 - 7 = 6 |
From the above solution, now we have to find the solution for: m - 7 = 3
This is the solution when m = 10 (in the table)
Thus, m = 10 is the solution of the given equation.
