Answer:
x = 9 and y = -13
Step-by-step explanation:
7x + y =50.... eq 1
4x + y =23....eq 2
Subtract eq 2 from eq 1
7x + y = 50
-
4x + y = 23
This becomes;
7x - 4x + y - y= 50 -23
3x = 27
Divide both sides by the coefficient of x; 3
x = 9
Slot in the value of x in eq 1
7 (9) + y = 50
63 + y = 50
Subtract 63 from both sides
63 - 63 + y = 50 - 63
y = -13
