8x加上x=46.
13x-6.8x+x=46.8
7.2x=46.8
x=6.5

X=6.5

(13-6.8 1)x=46.8 x=46.8/7.2=7.5 13x-6.8x x=46.8 7.2x=46.8 x=6.5 13x-6.8x x=46.8 7.2x=46.8 x=6.5 ..

13x-6.8x+x=46.8
13x-5.8x=46.8
7.2x=46.8
x=46.8/7.2
x=6.5

13X-6.8X+X=46.8
7.2X=46.8
X=6.5
可以把13X-6.8X+X化简。
13个X减去6.8个X等于6.2个X。6.2个X再加一个X等于7.2个X。
所以7.2个X等于46.8。
一个X就可以用46.8除以7.2

您好!应该是:
13x-6.8x+x=46.8 先把13x减去6.8x=6.2x,
6.2x+x=46.8 然后6.2x+x=7.2x,
7.2x=46.8 最后拿46.8÷7.2=6...

您好!应该是:

6.2x+x=46.8 然后6.2x+x=7.2x,
7.2x=46.8 最后拿46.8÷7.2=6.5,
x=6.5 所以x=6.5
希望对你有帮助!
