(x+1)/4=x-(5x-1)/3求解方程,(x+1)/4=x-(5x-1)/3求解方程,(x+1)/4=x-(5x-1)/3求解方程,(x+1)/4=x-(5x-1)/33(x+1)=12-4(5

(x+1)/4=x-(5x-1)/3求解方程,
(x+1)/4=x-(5x-1)/3求解方程,

(x+1)/4=x-(5x-1)/3求解方程,
(x+1)/4=x-(5x-1)/3
3(x+1)=12-4(5x-1)
3x+3=12-20x+4
3x+20x=12+4-3
23x=12
x=12/23

(x+1)/4=x-(5x-1)/3
去分母:3(x+1)=12x-4(5x-1)
去括号:3x+3=12x-20x+4
合并同类项:11x=1
系数化为1:x=1/11

x=1

x+1=4x-4/3*(5x-1)=(4-20/3)x+4/3=-8x/3+4/3
11x/3=-1/3
x=-1/11

(x+1)/4=x-(5x-1)/3
3(x+1)=12x-4(5x-1)
3x+3=12x-20x+4
3x+20x-12x=4-3
11x=1
x=1/11
