Answer:

x = 8, y = 6

Step-by-step explanation:

2x + 5y = 46______(1)

3x - 2y = 12_______(2)

(1) x 3 --> 6x + 15y = 138

(2) x 2 --> 6x -4y = 24

(1) - (2) --> 19y = 114

                    y = 6  sub into (2)

3x - (2 x 6) = 12

             3x = 24

               x = 8

Please mark as brainliest!!!
