Question

Pick out the solution from the values given in the brackets against each equation :
Show that the other values do not satisfy the equation.
$5m=60$ $(10,5,12,15)$

Answer 1

$5m=60$

$\Rightarrow m=\frac{60}{5}=12$

Hence the value of $m=12$.

Now,

For $m=10$

$5\times 10=50\ne 60$

For $m=5$

$5\times 5=25\ne 60$

For $m=15$

$5\times 15=75\ne 60$

Hence the other values given do not satisfy the given equation.
