What are the values of t and u?

 

Hello Guest!

 

    \(3t+(u-46)+49=180\)                  | sort by

 \((u-46)+(7t-23)=180\)                  | sort by

               \(3t+u-177=0\)                       | \(\times (-1)\)

            \(-3t-u+177=0\)                    

               \(\underline{7t+u-249=0}\)                       | add

                         \(4t-72=0\)                        | + 72

                                  \(4t=72\)                      | : 4

                                    \(t=18\)

                \(3t+u-177=0\)                       | + 177 - 3t

                                    \(u=177-3t\)          | t  deploy

                                    \(u=177-3\times 18\)

                                    \(u=123\)

                                    laugh  !
