60×0.8+1.2×括号里X碱60等于x×0.88怎么解60×0.8+1.2×括号里X碱60等于x×0.88怎么解60×0.8+1.2×括号里X碱60等于x×0.88怎么解左边=48+1.2X-72

60×0.8+1.2×括号里X碱60等于x×0.88怎么解
60×0.8+1.2×括号里X碱60等于x×0.88怎么解

60×0.8+1.2×括号里X碱60等于x×0.88怎么解
左边=48+1.2X-72=1.2X-24
右边=0.88X=左边
所以1.2X-0.88X=24
0.32X=24
X=75

48+1.2(x-60)=0.88x
48+1.2x-72=0.88x
1.2x-24=0.88x
0.32x=24
x=75
