x乘以1200等于括号12减x反括号乘以800这个方程怎么解
答
x*1200=(12-x)*800
x*1200=9600-800x (去括号)
2000x=9600 (移项,合并同类项)
x=4.8
答
(1200+800)X=800×12;得X=9600/2000=4.8
答
1200 X = (12- X ) x 800
1200X + 800X = 9600
2000X = 9600
X =4.8
答
1200x=(12-x)X800
1200x=9600-800x
1200x+800x=9600
2000x=9600
x=4.8
答
1200 X = (12- X ) x 800
1200X + 800X = 9600
2000X = 9600
X =4.8
