Answer 1

y x 126 - y=125x36

=>125xy=125x36

=>y=36

Answer 2

y x 126 - y = 125 x 36

y x ( 126 - 1 ) = 4500

y x 125 = 4500

y = 4500 : 125

y = 36

Answer 3

 y x 126 - y = 125 x 36

 y x 126 - y = 4500

      y + 126 = 4500 + y

         y + y =  4500 - 126

         y + y = 4374

         y + y = 4374 : 2 

            y    = 2187

Answer 4

y x 126 -y x 1 =125 x 36

y x(126-1)=4500

y x 125 =4500

y=4500 :125=36

Answer 5

  y.126-y=125.36

=>y.126-y.1=125.36

=>y.(126-1)=125.36

=>y.125=125.36

=>y=125.36:125

=>y=36.

Answer 6

y x 126 - y = 125 x 36
y x ( 126 - 1 ) = 4500
y x 125 = 4500
y = 4500 : 125
y = 36
