x1+x2+x3+x4+x5=k;3x1+2x2+x3+x4-3x5=0;x2+2x3+2x4+6x5=h;5x1+4x2+3x3+3x4-x5=4;k,h为何值时有解
求解一个方程急 X(1次方)+X2+X3=5 X2+X3+X4=1 X3+X4+X5=-5 X4+X5+X1=-3 X5+X1+X2=2 求X的值,
SIN(X)=X-X3/3!+X5/5!-X7/7!+.X3代表3次方,/代表除法 用C编程啊,
写出x的各个答案就行了.x1+x2+x3=5x2+x3+x4=1x3+x4+x5=-5x4+x5+x1=-3x5+x1+x2=2
x1-x2+x3=1x2-x3+x4=21若x1,x2,x3,x4,x5满足方程组 x3-x4+x5=3x4-x5+x1=4x5-x1+x2=5求x2 x3 x4的值2已知 x1+x4+x6+x7=39 x2+x4+x5+x7=49 x3+x5+x6+x7=41 x4+x7=13 x5+x7=14 x6+x7=9 x1+x2+x3+x4+x5+x6+x7=9求x7的值若x1,x2,x3,x4,x5满足方程组 x1-x
