Question

Simplify the following expression (3x/10)-2​

Answer 1

`(3x - 20)/(10)`

Explanation:

`(3x)/(10) - 2`

=
`(3x)/(10) - (2)/(1)`

The denominators of both fractions need to be the same. Therefore, algebraic manipulation will be applied:

`(3x)/(10) - [((10)/(10))((2)/(1))]`

=
`(3x)/(10) - (20)/(10)`

The resulting simplified fraction will have the same denominator and everything in the numerator level will be copied down:

=
`(3x - 20)/(10)`
