Y=-X-3
X+Y=4
You'll want to get X or Y by itself, which in this question it already is.
After that, use substitution (Plug -X-3 in place of Y in X+Y=4)
Equation should look like X+(-X-3)=4
Solve that equation
X+(-X-3)=4
X+(-X) cancels eachother out, leaving you with (-3)=4
Add 3 to both sides of (-3)=4, leaving you with 0=7
0 Can't equal 7, so this equation has no solutions
Answer:
N80
Step-by-step explanation:
One ruler is N60 and one pencil is N20.
The 9 is in the tenths place.
For the answer to the question above,
2x^4 + 22x^3 + 60x^2
<span>GCF: 2x^2 </span>
<span>2x^2(x^2 + 11x + 30) =
So the following factor for the problem above is
2x^2(x + 6)(x + 5)
</span>
If you want to double check, just multiply the answer.
I hope my answer helped you.
