To solve this problem, we should set up an equation, letting x be the unknown number.
9 + x = 0
Next, we should subtract 9 from both sides to cancel out the +9 on the left side of the equation and get the variable alone.
x = -9.
Therefore, the number you are looking for is -9.
Multpiply first equation by 3 and second by 5 to clear nasty faractions
-13x-6y=21
15x+2y=25
now see which ones we can clear
we can clear y
multiply second equation by 3 and add to the first equation
-13x-6y=21
<u>45x+6y=75 +</u>
32x+0y=96
32x=96
divide both sides by 32
x=3
sub back
15x+2y=25
15(3)+2y=25
45+2y=25
minus 45 from both sides
2y=-20
divide both sides by 2
y=-10
x=3
y=-10
(3,-10)

The answer will be 6/8 because you will add 1/8 to 5/8
