X-0.4X=36
(X+X)+(X-X)+(X*X)+(X/X)=100
x+2x×10=10x+2x+36
0.2x+0.4x=12 x=?20x+x=420 x=?
解方程 麻烦帮下忙6X-4.8*0.4=5.28 12.58X+X=108 2X(3.5+X)=36 24*3+2X=9
x+x=x+15
36-(3x-10)=x-2x 3.2x=14.2-1.5x
x+x+x+y=52 y+y+y+x=36求x
(10 x 2x + 2x)- (10x + 2x) =36
若2^x+1 X 3^x+1 = 36^x.求x的值
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!)+.
