Answer:
y=4 , x= 12
Step-by-step explanation:
This question deals with linear equations so, with this problem, subsitution is the easiest form of solving.
x + y = 16
8 + y = x
Now you know that x = 8 + y, so replace it in the opposing equation.
8 + y + y = 16 (simplfy)
8 + 2y = 16 (subtract 8 from each side)
2y = 8 (divide each side by 2)
y = 4
plug into other formula
8 + 4 = x
x =12
