\(804-x-155=318\)
\(804-x=318+155\)
\(804-x=473\)
\(x=804-473\)
\(x=331\)
\(804-x-155=318\)
\(804-x=318+155\)
\(804-x=473\)
\(x=804-473\)
\(x=331\)
804 - x - 155 = 318
804 - x = 318 + 155
804 - x = 473
x = 804 - 473
x = 331
804-x-=318+155
804 -x= 473
x=804-473
x=331
Vậy x = 331
804-x-155=318
804-x=155+318
804-x=473
x=804-473
x=331
x = 649 à ?
