0.15x+0.2×(66-x)=[5x+9×(66-x)]×0.18 解x 急
0.15x+0.2×(66-x)=[5x+9×(66-x)]×0.18 解x 急
0.15x+0.2×(66-x)=[5x+9×(66-x)]×0.18
0.15x-0.2x+13.2=(594-4x)*0.18
13.2-0.05x=106.92-0.72x
0.67x=93.72
x=9372/67
0.15x+13.2-0.2x=0.9x+106.92-1.62x
0.67x=93.72
x约等于139.88
0.15x+0.2×(66-x)=[5x+9×(66-x)]×0.18
0.15x+13.2-0.2x=(5x+594-9x)*0.18
13.2-0.05x=106.92-0.72x
0.72x-0.05x=106.92-13.2
0.67x=93.72
x=93.72/0.67
x≈139.88
0.15+13.2-0.2x=(594-4x)*0.18
13.35-106.92=-0.72x+0.2x
0.5x=93.57
x=187.14
