I believe what your asking is just multiplying it together so 5p(p-3) would be 5p2-15p. the p2 is p squared or a little 2 on top of the p. Hope I helped!

Answer :
m = 13.4/4.65
Step by step :
7.8 + 2(0.75m + 0.4) = -6.4m + 4(0.5m - 0.8)
7.8 + 2.75m + 0.8 = -6.4m + 4.5m - 4.8
2.75m + 6.4m - 4.5m = -7.8 - 0.8 - 4.8
4.65m = 13.4
m = 13.4/4.65
