(56-x)÷(34-x)=3

问题描述:

(56-x)÷(34-x)=3

(56-x)=3(34-x)
56-x = 102 - 3x
-x+3x=102-56
2x=46
x=23

方程两边同乘以(34-x)
56-x=3×(34-x)
56-x=102-3x
2x=102-56
2x=46
x=23

(56-X)=3(34-X)
56-X=102-3X
2X=46
X=23
累死我了

56-x=3*(34-x)
56-x=102-3x
2x=46
x=23

(56-X)=3(34-X)
56-X=102-3X
2X=46
X=23

56-x=3(34-x)
56-x=102-3x
3x-x=102-56
2x=46
x=23
