Answer:

Step-by-step explanation:

3x - y = 23 --------1

x/3 + y/4 = 4 ---------2

solving for 2-

x/3 + y/4 = 4

LCM = 12

4x + 3y = 48

taking 1 and 2

3x - y = 23

4x + 3y = 48

(3x - y = 23)3

4x + 3y = 48

9x -3y = 69

4x + 3y = 48

13x = 117

Therefore x = 9 -------3

substituting 3 in 2

4(9) + 3y = 48

36 +3y =48

3y = 12

Therefore y 4
