$= > 15n + 10 = 40$

=>Here ,on left hand side 10 is positive and when we shift it to the Right hand side it sign gets changed say -ve.

$= > 15n = 40 - 10$

$= > 15n = 30$

=>on the left side 15 is being multiplied by n so ,to find out the n's value it divides 30 on the right side and we obtain n =2

$= > n = \frac{30}{15} = 2$

Therefore,the value of n is 2
