Question

Tìm x

* X x 5 + 122 + 236 = 633 

Answer 1

x x 5 + 122 + 236 = 633

(x x 5 ) + 122 + 236 = 633

(x x 5 ) + 358           = 633

(x x 5 )                     = 633 -358

x x 5                         = 275

x                               = 275 : 5

x                              = 55

Answer 2

(x x 5 ) + 122 + 236 = 633

(x x 5 ) = 633 -358

x = 275 : 5

x = 55
