2/5x = - 10
2 = -10 X 5x
2 = -50 x
2/-50 = x
1/-25 = x

Multiply both sides by 5x and you get 2 = -50x
Divide both sides by -50 and you get -2/50 = x or -1/25 =x

Multiply both sides by the reciprocal of 2/5 which is 5/2
(5/2)(2/5)x= (-10)(5/2)
x = -25

2/5x = -10
2 = (-10)*5x
2 = (-50)X
X = - 2/50
X = - 1/25.
If ur question is (2/5)x = -10
then
X = -25.

2/5x = -10
(2/5x)*5x = (-10)*5x
2 = -50x
x = 2/-50
x = -0.04
hope it helps.

do you mean
2/(5x)=-1 ? multiply both sides by 5x
2=-50x divide both sides by -50
x=-2/50=-1/25=-0.04
x=-0.04
or
(2/5)x=-10?
multiply both sides by 5/2
x=-10*5/2=-25
x=-25

multiply both sides by 5/2
2/5* 5/2 x=-10* 5/2
1x=-25
x=-25
