Question

解方程2（2-3y)/0.01-4.5=0.03-3y/0.03-9.5

Answer 1

（2-3y)/0.01-4.5=0.03-0.03y/0.03-9.5
2-3y-0.045=（1-y）*0.01-0.095
2-3y-0.045=0.01-0.01y-0.095
3y-0.01y=2-0.045-0.01+0.095=2.04
2.99y=2.04
y=2.04/2.99=204/299

Answer 2

2（2-3y)/0.01-4.5=0.03-3y/0.03-9.5
200(2-3y)-4.5=0.03-100y-9.5
400-600y-4.5=0.03-100y-9.5
-600y+100y=0.03-9.5-400+4.5
-500y=-404.97
y=0.80994

Answer 3

2(2-3y)\0.01-4.5=0.03-3y\0.03-9.5
-2y\0.01=0.03-3y\0.03-9.5+4.5
-200y=-100y-4.97
-100y=-4.97
y=0.0497
