1/3X+1/4X+18=3/4X怎么解分步算给我,1/3X+1/4X+18=3/4X怎么解分步算给我,1/3X+1/4X+18=3/4X怎么解分步算给我,先把分母变成12即4/12X+3/12X+1
1/3X+1/4X+18=3/4X 怎么解分步算给我,
1/3X+1/4X+18=3/4X 怎么解
分步算给我,
1/3X+1/4X+18=3/4X 怎么解分步算给我,
先把分母变成12即4/12X+3/12X+18=9/12X
再合并同类项得2/12X=18
X=108
18=3/4X -1/4X-1/3X
3/4X -1/4X-1/3X=18
1/6X=18
X=18*6
x=108
题目给清楚点
x-1/x-2-x-3/x-4=x-2/x-3-x-4/x-5怎么做?
1+x+x^2+x^3+x^4+x^5+x^6+x^7+x^8+x^9+x^10+x^11+x^12=97.8x+x^2+x^3+x^4+x^5+x^6+x^7+x^8+x^9+x^10+x^11+x^12=97.8 好多年没有用过过数学公式了 想不起来怎么算了 想知道 X值是多少
*-----------------------------------------------*| 6 4 X | 8 X X | X X 5 || X X X | X X X | X 7 8 || X X X | X X X | X X X ||---------------+---------------+--------------- || X X X | X X X | 5 1 X || X X X | X 6 X | X X X || 8 X X | 3 5 X | 2 X X ||
