(2.4+x)×1.5=5.4怎么解方程

1.5(2.4+x)÷2=5.4 解:1.5(2.4+x)=5.4*2 2.4+x=108÷15 2.4+x=7.2 x=4.8

解:抄袭(bai2.4 + x)*duzhi1.5 = 5.4 2.4 * 1.5 + 1.5x = 5.4 3.6 + 1.5x = 5.4 1.5x = 5.4 - 3.6 1.5x = 1.8 x = 1.8 ÷dao 1.5 x = 1.2

{x+2.4}*0.75=5.40.75x+1.8=5.4 0.75x=3.6 x=4.8望选择为满意答案,您的采纳是我们坚持的动力.

(x+ 2.4)x1.5÷2=5.4解:x+2.4=5.4*2÷1.5x+2.4=7.2x=7.2-2.4x=4.8

(x十2.4)x1.5=5.4解:1.5x+2.4*1.5=5.4 1.5x=5.4-3.6 x=1.8÷1.5 x=1.2供参考

原式可化为(x+2.4)*1.5=5.4,x+2.4=5.4*2/3, x=-0.6

2(x-1.5)=5.4 (x+2.4)*3=9.6 8*(x+2.9)=72 2x-3=5.4 3x+7.2=9.6 8x+23.2=72 2x=8.4 3x=2.4 8x=48.8 x=4.2 x=0.8 x=6.1

3+x=5.4解:移项得x=5.4-3 =2.4 将x=2.4带入验算得 3+x=3+2.4=5.4成立 所以方程解为 x=2.4

3+x=5.4x=5.4-3(移项)x=2.4检验:3+2.4=5.4,符合题目,所以x=2.4

1.25x2.4+1.5x=5.4x=(5.4-1.25x2.4)/1.5x=1.616.9/x=1.3x=16.9/1.3x=13
