Alright so this is what you do.
You need to isolate one variable so that it is y = or x =
Lets go with y = for the first one
-x +3y = -6
x - 3y = 6
Isolate y = by adding x for the first one and then subtracting x from the second one.
3y = -6 + x
-3y = 6 - x
You would then divide the second one by -3 and divide by 3 in the first one.
y = (-6 +x) / 3
y = (6 -x) / -3
Since this is what y = you can put them together.
-6+x) / 3 = 6-x)/-3 (I put one parenthesis for convenience)
This equation is now set and you aren't done yet.
You can take out -1 from each side. This makes it no solution since you must always multiply by -1.
(6+x) / 3 = -1( (6+x) / 3)
Try the second one on your own!
<span>reater than 3 tens 6 ones" probably means greater than 36, so maybe it's 37, 38, 39, and so on, up to 51. "It has more than 6 ones" probably means that it's got 7 or more in the ones place. so 40, 41, up to 46, and 50 and 51 can't be it. So we're left with 37, 38, 39, 47, 48, or 49 as possibilities for what Ava picked.</span>
The difference between the two polynomials is 11x²3y³ - 4xy².
<h3>What is the Difference between the Polynomials?</h3>
The difference between two polynomials is the result you get by subtracting one from the other.
Thus:
= (4x²2y³ + 2xy² – 2y) – (–7x²y³ + 6xy² – 2y)
= 4x²2y³ + 2xy² – 2y + 7x²y³ - 6xy² + 2y
= 11x²3y³ - 4xy²
