2.6x+3.2x=0.174

2.6x+3.2x=0.174 求(x-2.6)+(x-3.2)=x+2.8的解 2.6x-x-0.1x=0.75 （X+X)+(X-X)+(X*X)+(X/X)=100 360-x=2.6x x+180%x=3.2 x-0.36x=3.2 x*x*x*x*x=80000? x*x*x=504 x*x*x=504 （x+x）+(x-x)+(x/x)=11.2 求x 的值.x +3.5x =9.9;4.25x -x =4.55;10x -2.7x =58.4;6.8x +3.2x =100 f(x)=x,x x+x=x+15 X(X-1)=X 180=( )x( )x( )x( ) ×( ) x+3.2x=4.8 16+7x=45 5.2x-x=32.4 3.2x+2.6(6-X)=18 10x+18(10-x)=140这叫做什么方程 (x+30)*(x-18)=x*x
