X * 37 = 8888

X        = 8888/37

\(x=\frac{8888}{37}\) 

X * 26 + 899 = 1393

X * 26           = 1393 - 899

X * 26           = 494

X                  = 494 /26

X                  =  19

2000 - 54 * X = 1136

          54 * X = 2000 - 1136

          54 * X = 864

                 X = 864 / 54

                 X = 16

 X * 27 * 16 = 864

 X *  432     = 864

 X               = 864 /432

 X               =  2
