如果 X×14分之5=Y×15分之14=1,那么5X-2Y,等于多少?请答案打中文,别打 数字.
x=5分之14Y=14分之15,那么5X-2Y=5乘以5分之14减去2乘以14分之15=7分之87=11又7分之4

求未知数X的值X+6分之1X等于15分之14 X除以5分之4等于28分之15
X+6分之1X等于15分之14 首先将左边分数的分子加上6减去6 然后左边就可以化简为1-X+6分之6 所以把15分之14 向左移 右边等于0 左边就是15分之1减去X+6分之6 然后在把分母乘过去 最后就可以得到x等于84X除以5分之4等于28分之15 首先等号左边可以算下 应该等于四分之五x 然后等式两边都乘以4 那么就可以得到5x等于七分之十五 所以x就等于七分之三
