Expert Answer:

3x - y=23 → y = 3x - 23 ...(1)
 
 
begin mathsize 16px style straight x over 3 plus straight y over 4 space equals space 4 rightwards double arrow 4 straight x space plus space 3 straight y space equals 48 space... left parenthesis 2 right parenthesis end style
 
Substitute the value of y from (1), into the equation (2), we get
 
4x + 3(3x - 23) = 48
→ x = 9
y = 3x - 23 = = 3(9) - 23 = 27 - 23 = 4
 
Therefore, the values of x and y are 9 and 4 respectively.
