Question

200-18:(372:3xy-1)-28=166

y?

 

Answer 1

200-18:(372:3xy-1)-28=166 

=> 200 - 18 : ( 126 x y -1 ) - 28 = 166

=> 200 - 18 : ( 126 x y -1) = 166 + 28 = 194

=> 18 : ( 126 x y - 1) = 200 -194 = 6

=> 126 x y - 1 = 18 : 6 = 3

=> 126 x y = 3 +1 = 4

=> y =  4  : 126

=> y =  2/63

Answer 2

200-18:(372:3xy-1)-28=166 

=> 200 - 18 : ( 126 x y -1 ) - 28 = 166

=> 200 - 18 : ( 126 x y -1) = 166 + 28 = 194

=> 18 : ( 126 x y - 1) = 200 -194 = 6

=> 126 x y - 1 = 18 : 6 = 3

=> 126 x y = 3 +1 = 4

=> y =  4  : 126

=> y =  2/63

Answer 3

y=2/63

Answer 4
