2.5x+1.5x=10

(x+2)(x^2+5x-10)-(x+2)^2(x-1),其中x=1.5(x+2)(x^2+5x-10)-(x+2)^2(x-1)＝(x+2)[(x^2+5x-10)-(x+2)(x-1)]＝(x+2)[(x^2+5x-10)-(x^2+

(x+2)(x^2+5x-10)-(x+2)^2(x-1),其中x=1.5,题目是这个吗?。。。。。。路过

x+x+(x*50%)=1.5X?x+x+0.5*x=1.5x2.5x=1.5xx=0

2(x+1)-(3-x)=2(1.5x-2.5)2(x-1)-(3-x)=2(1.5x-2.5)2x-3x+x=2+3-5-x+x=00=0这个方程无解

180/x+180/(x-2.5)=360/(x-1.5)180/x+180/(x-2.5)=360/(x-1.5)(180x-450)/(x²-2.5x)+180x/(x²-2.5x)=360/(x-1.5)(360x

计算：10/x-（10/2.5x）=1.510/x-（10/2.5x）=1.510/x-4/x=1.56/x=1.5x=6÷1.5x=4如果本题有什么不明白可以追问,如果满意请点击“选为满意答案”
