X-4y=-12
4x-y=12
eliminate y's
multily 2nd equaiton by -4 and add to top one
x-4y=-12
<u>-16x+4y=-48 +
</u>-15x+0y=-60
-15x=-60
divide both sides by -15
x=4
sub back
x-4y=-12
4-4y=-12
minus 4 both sides
-4y=-16
divide both sides by -4
y=4
x=4
y=4
(x,y)
(4,4)<u>

Answer:
<em>8 14/45</em>
Step-by-step explanation:
First, place 8/9 anywhere there is a y:
6+8(8/9-3/5)
Next, do what is in the parenthesis. Make both fractions have the same denominator.
6+8(40/45-27/45)
And now subtract:
6+8(13/45)
Now, multiply 8 and 13/45:
6+ 104/45
Convert the fraction to a mixed fraction:
2 14/45
Finally, add 6:
8 14/45
