Answer:
x = -1
Step-by-step explanation:
5x + 2y = 1 (eqn 1)
y = -x + 2 (can also be written as y = 2 - x)
subbing y = -x +2 in eqn 1,
5x + 2(2-x) = 1
5x + 4 - 2x = 1
3x = 1 - 4
3x = -3
x = -1

Your answer would be C.
Answer:
-4x + 5y
Step-by-step explanation:
-1/6 x 24 x simplifies to -1 times 4x, which is -4x. -1/6 times -30y simplifies to -1 times -5y, which is 5y.
Answer: Our required answer will be
![11x^2y^3-4xy^2](https://tex.z-dn.net/?f=11x%5E2y%5E3-4xy%5E2)
Step-by-step explanation:
Since we have given that
![(4x^y^3+2xy^2-2y)-(-7x^2y^3+6xy^2-2y)](https://tex.z-dn.net/?f=%284x%5Ey%5E3%2B2xy%5E2-2y%29-%28-7x%5E2y%5E3%2B6xy%5E2-2y%29)
We need to get the difference:
1) We first open the second bracket and make appropriate change in signs :
![4x^y^3+2xy^2-2y+7x^2y^3-6xy^2+2y](https://tex.z-dn.net/?f=4x%5Ey%5E3%2B2xy%5E2-2y%2B7x%5E2y%5E3-6xy%5E2%2B2y)
2) Gather the like terms together :
![4x^2y^3+2xy^2-2y+7x^2y^3-6xy^2+2y\\\\=4x^2y^3+7x^2y^3+2xy^2-6xy^2-2y+2y\\\\=11x^2y^3-4xy^2](https://tex.z-dn.net/?f=4x%5E2y%5E3%2B2xy%5E2-2y%2B7x%5E2y%5E3-6xy%5E2%2B2y%5C%5C%5C%5C%3D4x%5E2y%5E3%2B7x%5E2y%5E3%2B2xy%5E2-6xy%5E2-2y%2B2y%5C%5C%5C%5C%3D11x%5E2y%5E3-4xy%5E2)
Hence, our required answer will be
![11x^2y^3-4xy^2](https://tex.z-dn.net/?f=11x%5E2y%5E3-4xy%5E2)
