〔(x+52.9)*5-3.9343]/0.5-10x=521.1314方程结果多少?请列出解题步骤.

问题描述:

〔(x+52.9)*5-3.9343]/0.5-10x=521.1314方程结果多少?
请列出解题步骤.

[5x+264.5-3.9343]/0.5-10x=521.1314
20x+529-7.8686-10x=521.1314
10x+521.8314=521.1314
10x=-0.7
x=-0.07
呵呵,按照数学就是这样的解答了哈

[(x+52.9)*5-3.9343]/0.5-10x=521.1314(5x+264.5-3.9343)/0.5-10x=521.13145x/0.5+264.5/0.5-3.9343/0.5-10x=521.131410x+529-7.8686-10x=521.131410x-10x+529-7.8686=521.1314529-7.8686=521.1314可以看到:x经过上...
