Question

Pick out the solution from the values given within brackets:

$5\mathrm{x}=60$ $(10,5,12,15)$

Answer 1

Using Trail & Error Method we can obtain the solution of the equation $5\mathrm{x}=60$ among the bracket

Put $\mathrm{x}=10$ in the given equation,we get

$5\mathrm{x}=5\times 10=50$

Put $\mathrm{x}=5$ in the given equation, we get

$5\mathrm{x}=5\times 5=25$

Put $\mathrm{x}=12$ in the given equation, we get

$5\mathrm{x}=5\times 12=60$

Put $\mathrm{x}=15$ in the given equation, we get

$5\mathrm{x}=5\times 15=75$

Thus, based on the above results, it is evident that $\mathrm{x}=12$ is the solution of the given equation.
