Answer:
x = -4, y = 8
Step-by-step explanation:
y - 12 + 2y = 12
=> 3y = 24
=> y = 8
x = 8 - 12
=> x = -4
Answer:
x = -4
y = 8
Step-by-step explanation:
We can substitute:
=> (y - 12) + 2y = 12
=> 3y - 12 = 12
=> 3y = 12 + 12
=> 3y = 24
=> y = 24/3
=> y = 8
Now we can substitute 8 in for y, in any of the equation given to find x:
=> x = (8) - 12
=> x = -4
Hope this helps!
