0.5x-4×0.25=1.25 32:X=3/5:4/5 (1.5x+2)×0.5=1.6
问题描述:
0.5x-4×0.25=1.25 32:X=3/5:4/5 (1.5x+2)×0.5=1.6
答
0.5x-4×0.25=1.25
0.5x-1=1.25
0.5x=2.25
x=4.5
32:X=3/5:4/5
3/5x=128/5
3x=128
x=128/3
(1.5x+2)×0.5=1.6
1.5x+2=3.2
1.5x=1.2
x=0.8
答
0.5x-4×0.25=1.25 0.5x - 1 = 1.250.5x = 2.25x = 4.532:X=3/5:4/5 32÷x = 3/5 × 5/432 ÷ x = 3/4x = 42又2/3(1.5x+2)×0.5=1.6 拜托了各位!1.5 x +2 = 1.6 ÷ 0.51.5 x = 16/5 -10/5x = 6/5 × 2/3x = 4/5...
