Question 4(d)
Complete the table and by inspection of the table find the solution to the equation m - 7 = 3.
m5678910111213⋯⋯m−7⋯⋯⋯⋯⋯⋯⋯⋯⋯⋯⋯
m56789101112131415m−7−2−1012345678
The given equation is m−7=3.
By analysing the table above, we can understand that only m=10 satisfies the given equation.
∴m=10 is the solution.
