Whag was Bens number

Answer 1

Answer:

Ben's number was $\frac{3}{2}$.

Step-by-step explanation:

Given that:

Ben thinks of a number.

Let,

x be that number.

According to given statement;

Double of number plus 4 is equals to number multiplied by 10 and subtracting 8.

2x + 4 = (x*10) - 8

2x + 4 = 10x - 8

4 + 8 = 10x - 2x

12 = 8x

8x = 12

Dividing both sides by 8

$\frac{8x}{8}=\frac{12}{8}\\x=\frac{3}{2}$

Hence,

Ben's number was $\frac{3}{2}$.
