请高手们把下面几道解方程题做一下,要有过程的. 7.2X=64.8 0.5X+11.4=19.4 X/7.6=41.8

---

x=64.8/7.2=9
x=(19.4-11.4)/0.5=16
x=41.8/7.6=5.5

---

7.2X=64.8
X＝拦绝蠢核9

0.5X+11.4=19.4
X＝16

X/简档姿7.6=41.8
X=317.68

---

7.2X=64.8 0.5X+11.4=19.4 X/7.6=41.8
解: X=64.8/7.2解: 0.5X=19.4-11.4解: X=41.8*7.6
X=9 0.5X=8 X=317.68
X=16

7.2x=64.8 ; x=64.8/春行知7.2 ;x=9
0.5x+11.4=19.4 ;0.5x=8 ;x=16
x/扒消带颂7.6=41.8 ;x=41.8*7.6 ;x=317.68

---

7.2X=64.8 X=64.8/7.2 X=9 0.5X+11.4=19 0.5X=19-11.4 X=15.2 X/7.6=41.8 X=41.8*7.6 X=317.68
