Can someone please answer this question ASAP

x = 14

y = 37

Step-by-step explanation:

3x + 9x +12 = 180 {linear pairr}

    12x + 12 =180

         12x = 180 - 12

          12x = 168

             x = 168/12

x = 14

3x  = 3*14 = 42

4y - 10  + 3x = 180         {linear pair}

4y - 10 + 42 = 180

          4y + 32 =180

               4y  = 180 - 32

               4y = 148

                 y = 148/4

                y = 37
