2括号x+x+0.8括号除以3=1.2解方程

2*(2x+0.8)=3.62x+0.8=1.82x=1x=0.5

1.8/1.2 = (x+3)/x(1.8-1.2)/1.2 = (x+3-x)/x0.6/1.2 = 3/xx = 6

0.8+x=1.2 x=1.2-0.8 x=0.4

1.2÷X=0.8,X=1.2÷0.8,X=1.5.

x÷(1/2+2/3)=1.2x÷(1/2+2/3)=6/5x=6/5*(1/2+2/3)x=6/5*1/2+6/5*2/3x=3/5+4/5x=7/5

x=1.2*3=3.6

7X-3.2+X=287x+x=28+3.28x=31.2x=3.92(X+X+0.8)÷3=1.22(X+X+0.8)=1.2*3=3.6x+x+0.8=3.6/2=1.8x+x=1.8-0.8=1x=1/2=0.5

x÷(x+99)÷3=1.2解:x÷(x+99)=1.2x3 x÷(x+99)=3.6 x=3.6(x+99) x=3.6x+356.4 x-3.6x=356.4 -2.6x=356.4 x=-1782/13

x÷3=1.2两边同时乘以3,得:x=3.6
