Question

Two thirds of a number x decreased by 5 is 9 what is the number?

Answer 1

Two thirds of a number x :
`(2)/(3) *x`

Two thirds of a number x decreased by 5:

`(2)/(3) *x - 5`


Two thirds of a number x decreased by 5 is 9:


`(2)/(3) *x - 5=9`


now solve for x:

2/3 x = 9+5
2/3 x = 14
x = 14*3/2
x=21
