Question

Anwar think of a number . If he take away 7 from 5/2 of the number the result is 23

Answer 1

Answer:

Let the number Anwar thought of be 'x'

$\frac{5}{2}$ x - 7 = 23

$\frac{5}{2}$ x = 23 + 7

$\frac{5}{2}$ x = 30

x = 30 ÷ $\frac{5}{2}$

x = 30 x $\frac{2}{5}$

x = 6 x 2

x = 12

∴ The number Anwar thought of was 12
