Answer:
1/2 or .5
Step-by-step explanation:
solve for x in the bottom equation
x = 4 - 8y
substitute the equation for x back into the top equation
4(4- 8y) - y = 3y + 7
solve for y
36y = 9
y = 1/4
substitute y back into the equation solving x
x = 4 - 8(1/4)
solve for x
x = 4 - 2
x = 2
xy = 1/4 * 2
xy = 1/2
