Answer:
X = 2, Y = 0
Explanation:
Add the two equations together to cancel out -4y and +4y
leaving you with:
8x = 16
8x = 16
divide both sides of the equation by 8 to get x on its own (8x/8 = x, 16/8 =2)
leaving you with:
x = 2
substitute the value of x back into the equation to calculate y (it can be either equation, top or bottom):
8(2) - 4 y = 16
8 x 2 = 16
leaving you with:
16 - 4y = 16
subtract 16 from both sides to get 4y on its own
leaving you with:
-4y = 0
so y = 0, and x = 2
