Question

how to solve this further???

Answer 1

(27n-19)/15=(25n+7)/15
=27n-19=25n+7. (multiply 15 in both side)
27n-25n=19+7
2n=26
n=13
i hope this solution would help you

Answer 2

on cross multiplication we get
(27x-19)*15 = 15*(25x+7)
405x - 285 = 375x + 105
405x - 375x = 105+285
30x= 390
x=390/30
x=13
