x xxxx substitute x xx the second ecuation using xxx first one

xxxxxx

 

xxxxxxxxxxxxxxxxxxxxxxxx

115.5-10.50x+6.75x=100.50

                           xxxxxxxxxxxxxxxxxxx

                           xxxxxxxxxx    xxx then we xxxxxxxxx - signal xx both sides

                            3.75x= xx

                                    x= 15/3.75
