X = 4
7(4)+14-3(4)=30
7(-11)+14-3(-11)=-30

Answer:
Step-by-step explanation
S.P of a t.v = rs 7200
Loss % = 25%
Therefore, C.P = S.P (100/100-loss)
=7200(100/100-25)
=7200 x 100/75
=9600
So,now C.P = 9600
Profit% = 25%
Therefore, S.P = C.P (100+profit/100)
=9600(100+25/100)
=9600 x 125/100
=12000
So,the price he should sell to gain 25%
=12000
