Question

How do you simplify the expression `15-(17x+5)/(5x+10)`?

Answer 1

`(58x+145)/(5(x+2))`

Explanation:

`"we require to express 15 as a fraction with a denominator"`
`"of "5x+10`

`rArr15=15xx(5x+10)/(5x+10)=(75x+150)/(5x+10)`

`rArr(75x+150)/(5x+10)-(17x+5)/(5x+10)larrcolor(blue)"common denominators"`

`"now subtract the numerators leaving the denominator"`

`=(75x+150-17x-5)/(5x+10)`

`=(58x+145)/(5x+10)" or "(58x+145)/(5(x+2)`
