Question

Which of the given equation does not have 4 as the solution?

• A. p + 5 = 9
• B. 14 - p = 10
• C. $\frac{20}{p}$ = 4
• D. 9p = 36

Answer 1

The correct option is C $\frac{20}{p}$ = 4

Option $A$ : $p+5=9$

$\therefore$ $p=9-5=4$

Option $B$ : $14-p=10$

$\therefore$ $p=14-10=4$

Option $C$ : $\frac{20}{p}=4$

$\therefore$ $p=\frac{20}{4}=5$

Option $D$ : $9p=36$

$\therefore$ $p=\frac{36}{9}=4$
