Question

For which system of equations is (–2, 3) the solution?
A.
3x + 2y = 0
4x + 3y = –1
B.
–3x + 4y = –6
2x + 5y = 11
C.
–x + 7y = 16
5x – 3y = 16
D.
–x + 7y = 23
5x + 3y = –1

Answer 1

Plug them, into the equations.
3(-2) + 2(3) = 0 that's correct
4(-2) + 3(3) = -1 that's wrong
so option A is wrong

Answer 2

Let's try option b.
-3(-2) + 4(3) = -6
6 + 12 = -6 Nope, not option b.

Answer 3

uh huh

Answer 4

Let's try option C.
-(-2) + 7(3) = 16
4 + 21 = 16 nope..

Answer 5

Through process of elimination, you know that option D is your correct answer.

Answer 6
