Answer:
x = 2 y=0
Step-by-step explanation:
We can solve using elimination method
8x - 4y = 16 __________(1)
8x + 4y =16 ___________(2)
Subtract equation (2) from equation (1)
-8y = 0
Divide both-side of the equation by -8
-8y/-8 = 0/-8
y = 0
Substitute y=0 into equation (1)
8x - 4y = 16
8x - 4(0) = 16
8x = 16
Divide both-side of the equation by 8
8x/8 = 16/8
(On the left-hand side of the equation, 8 at the numerator will cancel-out 8 at the denominator leaving us with just x while on the right-hand side of the equation 16 will be divided by 8)
x = 16/8
x = 2
Therefore x = 2 and y=0
