The system of linear equations 5 x + 3 y = 3 and x + y = negative 1 is graphed below.

On a coordinate plane, 2 lines intersect at (3, negative 4).

What is the solution to the system of equations?
(–4, 3)
(–3, 4)
(3, –4)
(4, –3)

Alina fully simplifies this polynomial and then writes it in standard form. xy2 – 2x2y + 3y3 – 6x2y + 4xy2 if alina wrote the last term as 3y3, which must be the first term of her polynomial in standard form? xy2 5xy2 –8x2y –2x2y
