(30-x):(18+x)=(20+x):(32-x)
(x+30)*(x-18)=x*x
(16x-13)/(4x-3)-(20x-24)/(4x-5)=(32x-30)/(8x-7)-(40x-43)/(8x-9)求x
matlab中a=[x(11)/x,x(12)/x;x(21)/x,x(22)/x;x(31)/x,x(32)/x;x(41)/x,x(42)/x;x(51)/x,x(52)/x]咋错了
30x=30(32-x)
32-7X-5X=30
(16x-13)/(4x-3)+(40x-43)/(8x-9)=(32x-30)/(8x-7)+(20x-24)/(4x-5)....
(16x-13)/(4x-3)+(40x-43)/(8x-9)=(32x-30)/(8x-7)+(20x-24)/(4x-5)
(X+X)+(X-X)+(X*X)+(X/X)=100
X÷48%=X+(X+32)
30/x=30/(x-1.5)-x
0.8x=x-30 x=
x ( x-30)= -67.5 X=?
x-30-0.2x=0.5x
3X+30+X+X-15=?
x+35=(x+3x)*30%
60x(x-4)=30x
