Using Substitution Method.
Expressing x as a function of y (from the first equation) x = (8 +2y)/1
Substituting this expression into the second equation:
3(8-2y)/1-2y = 12
Simplifying this expression:
4y = -12
or
y = -3
Now, substituting y = -3 back into the x expressed as a function of y:
x = (8+2y)/1 = 2
