Answer:

Step-by-step explanation:

If the sum of the digits of a number is divisible by 9, then the number is divisible by 9.

So 6+7+8+5+Δ+4 = Δ + 30 has to be divisable by 9, and of course 0≤Δ≤9

36 is divisable by 9, so Δ has to be 6.

Answer:

$x=0.75, y=-0.25$

Step-by-step explanation:

We can add the two equations to eliminate $y$ and solve for $x$ .

$x+y+x-y=0.5+1$

$2x=1.5$

$x=0.75$

Now, we can find for $y$ by using substitution:

$x+y=0.5$ (given)

$0.75+y=0.5$

$y=-0.25$

Hope this helps :)
