           2x+3y·3y+2x=z
2(3.2)+3y·3y+2(3.2)=457.96
             6.4+9y+6.4=457.96
                   12.8+9y=457.96
                        -12.8=-12.8
                            9y=445.16
                             /9=/9
                              y=49.46222222
                              y=49.46
