Answer 2

The number does Riaz think is 15  

Step-by-step explanation:

Given as :

Statement

we subtract 7 from 2 the time of a number the result come to be 23

Let The number = x

According to statement

Left hand side = 7 subtracted from 2 time x

i.e                     = 2 x - 7                           .........1

Again

Right hand side = 23                               .........2

Now, equating left hand side of equation and right hand side equation

So,  2 x - 7 = 23

Or,  2 x = 23 + 7

Or,  2 x = 30

∴        x = $\dfrac{30}{2}$

i.e     x = 15

So, The number = x = 15

Hence, The number does Riaz think is 15  Answer
