1.5-x=0.25

x+ x+(x*50%)=1.5X? 1.5X=(1.5-0.25)(X+10) 1.5-x=0.25 （x-4)-(x+4)=0.25x 66=X+0.25X求X 0.25x+3.6=x解x 1.5x=x-1.6＊x x+(x-1.4)+1.5x=33. 30/x=30/(x-1.5)-x x-0.25=0.25x 0.3x＋7x-0.25x=21.58.7×(36-x)=04（不知道是x还是× 都解了吧）x或者×(x＋0.2)=1.27(x＋6)-3x=4x(2x＋5)3(x＋2)=4(x＋1)18-4x=2x-63.8x＋1.2x=256x＋1.5x=15呼呼.累死我了 着急 求MATLAB高手解救!为什么运行老是错误函数function f=myfun1(x);f=17.42+0.25*x(2)*(x(6)+2*x(7)+2*x(8)+x(9))-1.5*x(1)*(x(3)/2+x(4)+x(5)/2);约束function[c,ceq]=mycon(x);c(1)=x(4)/x(3)-5;c(2)=x(5)/x(4)-5;c(3)=x(7)/x(6)-5;c(4)=x(8)/x(7)-5;c x-0.25x+1=10.4x+0.25x-1 x-0.25x=0.
