Question

Which of the following is the solution to 13/(x+2) = 8/(x-1)?

Answer 1

`(13)/((x + 2)) = (8)/((x - 1))`

By cross - multiplication

`\implies13 * (x - 1) = 8 * (x + 2)`

`\implies13x - 13 = 8x + 16`

`\implies13x - 8x = 16 + 13`

`\implies5x = 29`

`\implies \: x = (29)/(5)`

`\implies \: x = 5.8`
