4.3x-1.5+3.2x =4.5
4.3x-1.5+3.2x =4.5
4.3x-1.5+3.2x =4.5
7.5x=6
x=0.8
4.3x-1.5+3.2x =4.5
4.3X--2.1+3.2X=4.5
x+ x+(x*50%)=1.5X?
3.2x=14.1-1.5x
8x+5x=1.3 4.5x-3.2x=3.9 5.5x-x=9.9 11x-7x-26=34 列方程
y=(3x^2-x√x+5√x-9)/√x 求导我算到4.5x^0.5-1+2x+4.5x^1.5 ,
4.3x-x+1.5x等于9.6
(X+X)+(X-X)+(X*X)+(X/X)=100
9x+7x-x=4.5
解方程 8.8x-2.4x=3.2 4.6x+5.4x=10.89 3(x+1.解方程8.8x-2.4x=3.24.6x+5.4x=10.893(x+1.7)=9.6(x-4.5)6=31.8
一些带有两个x的方程,x+3.5x=9.94.25x-x=4.5510x-2.7x=58.46.8x+3.2x=1007x+0.5x=1.5
1.5x=x-1.6*x
x+(x-1.4)+1.5x=33.
30/x=30/(x-1.5)-x
