A +7.5 nC point charge and a -2.0 point charge are 3.0 cm apart. What is the electric field strength at the midpoint between the two charges?

just give me the formula ?

q is a point charge. Your problem gives two of them. r is the distance from q to the midpoint. Pay attention to the signs of each q.
 
can you tell me the exact way to solve it ?

We're not allowed to do that.

Please reflect on what I said so far.
