Question

(x-4)/(2x+1)-3 can you help me with this question

Answer 1

`((x - 4))/((2x + 1)) - 3`
`=`
`(-7x- 7)/(3x + 1)`

Explanation:

Given

`((x - 4))/((2x + 1)) - 3`

Required

Solve

Express 3 as a fraction

`((x - 4))/((2x + 1)) - (3)/(1)`

Take LCM

`(x - 4 - 3(2x + 1))/(3x + 1)`

`(x - 4 - 6x - 3)/(3x + 1)`

Collect Like Terms

`(x - 6x- 4 - 3)/(3x + 1)`

Simplify like terms

`(-7x- 7)/(3x + 1)`

Hence:

`((x - 4))/((2x + 1)) - 3`
`=`
`(-7x- 7)/(3x + 1)`
