解方程百分之40X+21=37 X-百分之78X=2.2 X+百分之30X=26(1-百分之25)X=15 2X+百分之20X=3.3
(X+X)+(X-X)+(X*X)+(X/X)=100
x-40%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
x*x*x*x*x=80000?
(x-25)+(x-23)+(x-27)+(x-21)+(x-26)=x 求x
78-x=5x 求x
x-40%x-40%x=15
x+40=2x x=?
X×X+(40-X)=58
X乘以X等于40 ---------------------X=?
10x+x*x=40
(x+40%x)×85%-x=95
(x+40%x)×85%-x=95
4x+x=40x
40%x+70%x-x=1.8
请完成以下各题 注意:一道题和第二道题要分开40%x+21=37x-78%x=2.2x+30%x=26(1-25%)x=1540%x-30=152x+20%x=3.
