MAPLE解方程组

0.04q1+0.8q2+0.35q3+0.25q4=600000
0.09q1+0.02q2+0.3q3+0.4q4=700000
1928000p1/297+q1=6748000
1200p2+q2=1184000
23100p3/105+q3=441000
28000p4/815+q4=98000
p4/(815-p4)=10/11-2100000/(11q3)
p3/(1050-p3)=5/2-175000/q4
求解未知数，，我对MAPLE这个软件不熟，这是帮我朋友问的

Answer 1

代哪游脊码为：
solve({p3/磨辩(1050-p3) = 5/2-175000/q4, p4/(815-p4) = 10/11-(2100000/11)/q3, (1928000/297)*p1+q1 = 6748000, 1200*p2+q2 = 1184000, 220*p3+q3 = 441000, (5600/163)*p4+q4 = 98000, 0.4e-1*q1+.8*q2+.35*q3+.25*q4 = 600000, 0.9e-1*q1+0.2e-1*q2+.3*q3+.4*q4 = 700000}, {p1, p2, p3, p4, q1, q2, q3, q4});
