Question

What is the x-value in the solution to this system of linear equations?

2x − y = 11

x + 3y = −5

A) -3 B) -1 C) 2 D) 4

Answer 1

The answer is A) -3
ok

Answer 2

B) -1 is the answer I think

2x -y = 11 -y = -2x + 11 y = 2x -11 . 2x + 3y = 7 3y = -2x +7 . So, the point (5,-1) is the common solution. . 2(5)-11 = -1, correct
