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
58%x-23%x=2.
解方程:x-60%x=240 x+20%x=24 1-25%x=十六分之三 160%x-x=9 58%x-23%x=24 40%x+70%x-x=1.8
23x+50%x=42
(x-25)+(x-23)+(x-27)+(x-21)+(x-26)=x 求x
(X+X)+(X-X)+(X*X)+(X/X)=100
X×X+(40-X)=58
25x+x-x-23=25
(x+7)(x+5)-(x+1)(x+5)=42
78+x=27+x+23+x+16+x,
(x+x+23+x+50)=3x 怎么解
23x+29=x
x*x*x*x*x=80000?
5x+7=42 x/4.2=2 3.6x-x=3.25 2(x-3)=58
解方程((13x-x^2)/(x+1))(x+(13-x)/(x+1))=42
(13x-x^2)/(x+1)[x+(13-x)/(x+1)]=42
