(X+10)=75%(X+48-10)怎么算

(X+10)=75%(X+48-10)怎么算
( x + 10 ) = 75% ( x + 48 - 10 )
x + 10 = 75% ( x + 38 )
x + 10 = 75%x + 28.5
x - 75%x = 28.5 - 10
25%x = 18.5
x = 18.5 ÷ 25%
x = 74

0.25x=36-17.5
x=18.5/0.25
x=74

(x+12)(x-2)+(x+7)(x+8)-(x+5)(x-10),其中x=2 x-?x+110=75%x-10 怎样计算 x-?x+110=75%x-10 怎样计算 10x²+530x=75,x等于几? (x+7/x+6) +(x+9/x+8)=9x=(x+10/x+9) +(x+6/x+5) 解方程(x/x(x+2))+(x/(x+2)(x+4))+.+x/(x+8)(x+10)=1 X+X+X+(X-1)+(X-2)+(X-3)+(X-4)=10(X-3)+(X-4) 25％x+x=10 x=? X+X-10+X+8=100 80%x+30-x=10%x 10x+x*x=40 求x:x(10^x)=100 x^2+10x( )=(x+ )^2 x^2-10x=2-x 2x×x=10,求x x²-10x+()=(x-)² 3x-x(10-x)=15 x(x-20)=x+10
