Menentukan nilai dan

table attributes columnalign right center left columnspacing 0px end attributes row cell x plus 1 end cell equals cell x plus m end cell row cell x minus x plus 1 end cell equals m row 1 equals m row cell x minus 1 end cell equals cell x plus n end cell row cell x minus x minus 1 end cell equals n row cell negative 1 end cell equals n end table

Jadi, nilai m equals 1 comma space n equals negative 1 .
