So one way is to have a number close to 7
14.00000000000000000000001/2
21.00000000000000000001/3
28.000001/4
etc
I think the answer is b i've never learned this sorry :(
If we multiply the bottom equation by 2 and move x to the right, it becomes:
4y = 2x-38
Now we can substitute it for the 4y in the top equation:
3x + (2x-38) = -23 => 5x = -23+38 => 5x = 15 => x=3
Then 4y = 2*3-38 => y = -8
So the solution is (3,-8)
7,943,670,217,666,519,002
$63000 more
Just subtract $23000 from $86000.
