Question

If five times a number is equal to three times the sum of the number and 6, then find the number.

• A. 9
• B. 4
• C. 6
• D. 5

Answer 1

The correct option is A 9

$\text{Let the number be}x\text{.}$

$\text{5 times the number = 5x}$
$\text{3 times the sum of number and 6}=3(x+6)$

$\text{Hence the equation will be,}5x=3(x+6)$
$5x-3x=182x=18x=\frac{18}{2}x=9$

Therefore, the number is 9.
