x + 14y = 12...multiply by -1
x - 10y = 60
--------------
-x - 14y = -12 (result of multiplying by -1)
x - 10y = 60
---------------add
-24y = 48
y = -48/24
y = -2

x + 14y = 12
x + 14(-2) = 12
x - 28 = 12
x = 12 + 28
x = 40

solution is (40,-2)
subtract the equations
24y = = -48
y = -2

x + 14y = 12
x + 14(-2) = 12
x= 12 + 28
x = 40

solution (40, -2)

answer is A .  (40, -2)
