3(8x-y = 31)
5x+3y = 23
Multiply all terms in the top equation by 3:
24x-3y = 83
5x+3y = 23
Add both equations together in order to eliminate y:
29x = 116
Divide both sides by 29 to find the value of x:
x = 4
Substitute the value of x into the original equations to find the value of y:
Therefore: x = 4 and y = 1
