Is F = X- 1, E = X-2, D = X-3 and ∫ d+c-1= X.

∴C = X+1 dimension = x+1x+3 = 4 2.

E+D+C = F+B ... 2x-1= 2x-1... is not a feasible option F+E = B+C...X+4 = 2x-3...X = 7.

I think we should go more often. Next month, we will divide the amount.

& lt/p "( 1) to establish a cooperative relationship, m days. & lt/p "(116+1/24) m+116 * (12-m) =1. ( 1/ 16+ 1/24)N+ 1/24 *( 12-N)= 1，N = 8

All finished. Seek passage. Write it yourself. comment
