Question

(4+х)/8=9

(х/5+3)*6=48 

Answer 1

4+x=72                    (x+15)/3*6=48

x=72-4                     2(x+15)=48

x=68                         x+15=48:2

                                 x+15=24

                                  x=24-15

                                   x=9

Answer 2

4+x=72             x/5+3=8 

x=68                 x/5=5 

                        x=25
