I'm assuming that you mean
%285p%2F7%29-18=-43

The first step should be to "undo" the -18, by adding +18 to each side of the equation:
%285p%2F7%29+-18%2B18+=-43%2B18
%285p%2F7%29+=+-25

Next, to undo the 5%2F7, you can multiply both sides of the equation by 7%2F5:

%287%2F5%29%2A%285p%2F7%29=-25%287%2F5%29 Divide 5 into the -25, which gives you -5.
p+=+-5%2A7=-35
