Question

(2k-7)/5+1-(k-1)/3
Pls help

Answer 1

`(k-1)/(15)`

Explanation:

`((2k - 7))/(5) + 1 - ((k-1))/(3)`

`(3(2k -7))/(3 ( 5)) + (15 * 1)/(15 * 1) - (5(k-1))/(5 * 3)`

`(6k - 21)/(15) + (15)/(15) - (5k - 5)/(15)`

`((6k - 21) + 15 - (5k - 5))/(15)`

`((6k - 6) - (5k - 5))/(15)`

`(6k - 6 - 5k + 5)/(15)`

`(k - 1)/(15)` <------This is your answer

Hope this helps!
