Step-by-step explanation:

50*(x/90)*(90-X) = 10*X // - 10*X

50*(x/90)*(90-X)-(10*X) = 0

50*(x/90)*(90-X)-10*X = 0

5/9*x*(90-X)-10*X = 0

5/9*x*(90-X)-10*X = 0

50*x-5/9*X*x-10*X = 0

50*x-5/9*X*x-10*X = 0

5*(10*x-1/9*X*x-2*X) = 0

10*x-2*X = 0 // + -2*X

10*x = -(-2*X) // : 10

x = (-(-2*X))/10

x = X/5

5*(x-1/5*X) = 0

5*(x-1/5*X) = 0

( 5 )

5 = 0

x belongs to the empty set

( x-1/5*X )

x-1/5*X = 0 // + -1/5*X

x = -(-1/5*X)

x = 1/5*X

x = 1/5*X
