Question

Pick out the solution from the values given in the bracket next to each equation. Show that the other values do not satisfy the equation.
q/2=7 (7, 2, 10, 14)

Answer 1

Let us try all the values -

7 / 2 = 7

3.5 ≠ 7

--------------

2 / 2 = 7

1 ≠ 7

--------------

10 / 2 = 7

5 ≠ 7

--------------

14 / 2 = 7

7 = 7

---------------

∴ 14 is the right answer.

Answer 2

$\mathsf {trying \: all \: values}$

$\bf \frac{7}{2} = 7 \\ \bf 3.5 ≠ 7 \\ - - - - - - - - - \\ \bf \frac{2}{2} = 7 \\ \bf 1 ≠ 7 \\ - - - - - - - - -$
10/2=7
5≠7

--------------------------------------

14/2=7
7=7

------------------------------------

•°• So, 14 is the correct answer
