Solve. 2/5x= -10?

2/5 x = -10
2x/5 = -10
2x = 5(-10)
2x = -50
x = -50/2
x = -25

Guessing that you mean:-
(2/5) x = - 10
2x = - 50
x = - 25

But shouldn`t have to guess !!!!

The reason for different answers appearing is that you have no brackets in question.

2x/5=-10
2x= 5(-10)
2x= -50
x= -25

2/5x= -10

x= 2/5(-10/1)

x= -4

2/5x= -10
(0.4)x=-10
threfor
x=-10/0.4
x=-25

-0.04 !!

2/5x = -10/1
cross multiplication
gives -10*5x = 2
-50x = 2
x = 2/-50
x = 1/-25

x=-25
