2.2x%0.5x2=10用方程解出来

2.2x-0.5*2=102.2x-1=102.2x=10+12.2x=11 x=11÷2.2 x=5

2.2x 一 0.5x2 = 10 2.2x 一 1 =10 2.2X = 11 X = 5

2.2x-0.5x2=102.2x=11x=5

2.2x-0.5x2=10 2.2x-1=10 2.2x=11 x=5

27*31x=145837x=145 x=837分之1452.2x-0.5*2=102.2x-1=102.2x=10+12.2x=11 x=53*1.5+2x=11.54.5+2x=11.52x=11.5-4.52x=7 x=3.513x-7x=5.76x=5.7 x=0.95

2.2x-0.5*2=102.2x=10 0.5*2=11X=11/2.2=5

(1)-2+0.5x=10,移项得:0.5x=10+2,合并同类项得:0.5x=12,把x的系数化为1得:x=24,(2) 2x+10 5 = 3-2x 3 +1 . 去分母得:3(2x+10)=5(3-2x)+15,去括号得:6x+30=15-10x+15,移项得:6x+10x=15+15-30,合并同类项得:16x=0,把x的系数化为1得:x=0.

x=5解析:2.2x-0.5*2=102.2x-1=102.2x=1+102.2x=110.2x=1x=5

2.2 x-0.5*2=10 解:2.2x-1=102.2x=11 x=11÷2.2 x=5 祝学习进步.

解:1.7x=15 x=15÷1.7 x=8.82
