Question 3(d)

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.

$\frac{q}{2}=7(7,2,10,14)$

Answer 1

Given equation is $\frac{q}{2}=7$

$\begin{array}{cc}Valueofq& Valueof\frac{q}{2}\\ & \\ \left(i\right)7& \frac{7}{2}=3.5\\ & \\ \left(ii\right)2& \frac{2}{2}=1\\ & \\ \left(iii\right)10& \frac{10}{2}=5\\ & \\ \left(iv\right)14& \frac{14}{2}=7\\ & \end{array}$

Only case (iv) is satisfying the given equation.

$\therefore$ q=14 is the solution.
