3.14X×50=(X+10)×40这个方程怎么解,用X作未知数就行了

3.14X×50=(X+10)×40
157x=40x+400
157x-40x=400
117x=400
x=400/157

3.14Xx5=(X+10)x4
15.7X=4X+40
11.7X=40
X=400/117

3.14X*50/40=x+10
3.14x*1.25=x+10
3.925x*=x+10
3.925x-x=10
2.925x=10
x=10/2.925

3.14x ×5=(x+10)×4
15.7x=4x+40
11.7x=40
x=400/117

3.14X×50=(X+10)×40
(50×3.14)X=40X+400
157X=40X+400
117X=400
X=400/117

3.14x×50=﹙x+10﹚×40
15.7x=﹙x+10﹚×4
15.7x=4x+40
11.7x=40
x=400/117

3.14X×50=(X+10)×40
157x=40x+400
157x-40x=400
117x=400
x=117分之400

157x=40x+400
157x-40x=400
117x=400
x=400/117
