Answer:
x = 18 , y = 42
Step-by-step explanation:
27x + 14 = 500
-14 -14
This process above moves the +14 to the right hand side, making it negative 14
27x = 486
To find x, divide 27 by 486
x = 486/27
x = 18
600 = 12 + 14y
Move the 12 to the left hand side to remain the 14y
600 = 12 + 14y
-12 -12
588 = 14y
Divide 14 by 588
588/14 = y
y = 42
