(1-1/4)x:(50-x)=3:2 (1-1/4)x:(50-x)=3:
问题描述:
(1-1/4)x:(50-x)=3:2
(1-1/4)x:(50-x)=3:
答
x-0.25x/50-x=3/2
150-3x=2x-0.5x
x=100/3
答
(1-1/4)x:(50-x)=3:2
3(50-x)=2(1-1/4)x
150-3x=1.5x
4.5x=150
x=100/3
答
(1-1/4)x:(50-x)=3:2这道方程怎么解?
3x/2=150-3x;
9x/2=150;
x=300/9;
x=100/3;

答
(1-1/4)x:(50-x)=3:2 这道方程怎么解?(要过程)
(3/4)x:(50-x)=3:2
3/2 x = 150 - 3x
150 = 9/2 x
300 = 9x
x = 100/ 3
