Question

3.14X×50=(X+10)×40这个方程怎么解，我才读小学六年级，用X作未知数就行了

Answer 1

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

Answer 2

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

Answer 3

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

Answer 4

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

Answer 5

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