9x+3x=3.6 9x-3x=3.6
问题描述:
9x+3x=3.6 9x-3x=3.6
答
1. X=0.3
2. X=0.6
答
(1)9x+3x=3.6
12x=3.6
x=0.3
(2)9x-3x=3.6
6x=3.6
x=0.6
答
1.9x+3x=3.6
解:9x+3x=12x
9x+3x=3.6
12x=3.6
x=0.3
所以方程9x+3x的解为0.3
2. 9x-3x=3.6
解:9x-3x=6x
9x-3x=3.6
6x=3.6
x=0.6
所以方程9x-3x的解为0.6
答
解:
1.12x=3.6
x=3.6/12
x=0.3
2.6x=3.6
x=3.6/6
x=0.6
解毕
答
9x+3x=3.6
12x=3.6
x=3.6/12
x=0.3
9x-3x=3.6
6x=3.6
x=3.6/6
x=0.6
