1.2/0.6+0.4-0.2=1.5 在上面的算式中添上括号,是它的运算结果等于3/2
1.2/(0.6+0.4-0.2)=1.5
0.4(x-0.6)-1.5=1.2x-3.34

0.4(x-0.6)-1.5=1.2x-3.34的方程怎么解
matlab利用公式绘图画出C=4,2,1.5,1.2,1.15,1.10,1.05,1.026,0.95,0,9,0.8,0.6,0.4,0.2,0.1时的等值线图(contour函数),画出来的图与下图类似:[c,h]=contour(x,y,C[0.01,0.2,0.4,0.6,0.8,0.9,0.95,0.974,1.026,1.05,1.1,1.15,1.2,1.2105
0.4x-0.6=0.2x-1.8
0.4x-0.6=0.2x-1.8
1.8-0.4x=0.2x-0.6
(0.1*0.3*0.9+0.2*0.6*1.8+0.3*0.9*2.9)除以(0.1*0.2*0.4+0.2*0.4*0.8+0.3*0.6*1.2)
(0.1*0.3*0.9+0.2*0.6*1.8+0.3*0.9*2.9)除以(0.1*0.2*0.4+0.2*0.4*0.8+0.3*0.6*1.2)
0.2x-1.2=0.6+x
(+0.2)+(-0.2)+(+0.7)+(-0.3)+(-0.4)+(+0.6)+0+(-0.1)+(-0.6)+(+0.5)+(-0.2)+(-0.5)=?(+0.2)+(-0.2)+(+0.7)+(-0.3)+(-0.4)+(+0.6)+0+(-0.1)+(-0.6)+(+0.5)+(-0.2)+(-0.5)=?
0.4(x-0.2)+1.5=0.7x-0.38 (0.6x+420)÷(x+20)=3
(0.1x+0.4)/0.2-(0.2x-0.6)/0.3=1
0.2x-1.5=1-0.2分之x+0.4
