求x 的值.x +3.5x =9.9;4.25x -x =4.55;10x -2.7x =58.4;6.8x +3.2x
解方程:1.x/x+1-1=3/(x+1)(x-2) 2.3/x+2+1/x=4/x²+2x 3.2/3+x/
36-(3x-10)=x-2x 3.2x=14.2-1.5x
已知方程:①4x-2=3-x,②2x−13=−x3+2,③3.2x+2.6(6-x)=18,④3x=2+x中,解为x=1
用递归法求y=x-(x*x*x/3!)+(x*x*x*x*x/5!)-(x*x*x*x*x*x*x/7!)+.
3.2x+2.6x=7.2
解方程:3.2x=170%x+22.5 x=( )
