Question

If the equation (5x - 2x)/2 = 12 represents the sale of table lamps, where x represents the number of table lamps sold, then the value of x is .

• A. 7
• B. 8
• C. 3

Answer 1

The correct option is B 8

The given equation is $\frac{(5x-2x)}{2}$ = 12

5x - 2x = 2 $\times$ 12
$\Rightarrow$ 3x = 24
$\Rightarrow$ x = 8

Hence, the number of table lamps sold is 8.
