So we cant do anything until the 'y' in the 2nd problem is by the 2x. So after we move the 2x over the equation will look like this, "-2x+y=-6."
Now that that is set up we can make our equation.
(12x+5y=30) - (-2x+y=-6)
We have to multiply the second equation by -6 in order to cancle out the X's. That comes out to (12x-6y=36)
Now the equation looks like (12x+5y=30) - (12x+6y=36)
After you subtract you have (-y=-6)
divide by (-1) and you're left with y=6
<u><em>Answer:</em></u>
-23.4 at 9:00 a.m.
<u><em>Step-by-step explanation:</em></u>
Make a ratio with the given numbers: -13, 5.
I believe the "common number" for the ratio of 1 a.m. would be:
2.6<u> : </u>1 times 9 = 23.4<u> </u><u>:</u><u> </u>9
