Answer:
(5/6, 8/5)
Step-by-step explanation:
We multiply the second equation by 2, and then add the equations together.
12x+15y=34
-12x+10y=6
------------------
25y=40
We divide by 25 on both sides, and get that y = 8/5. We substitute y into either of the equations.
-6x +5(8/5)=3
Do the multiplication.
-6x+8=3
Subtract 8 from both sides.
-6x=-5
Divide by -6 on both sides.
x=5/6.
Hi!
The number has a zero in the denominator.
If a number has a 0 in it's denominator, then it's not rational
Division by 0 is undefined.
Hope this helps you!
