Hi there! The answer is A.
[tex]y = 3x + 4 \\ y = - 3x - 4[/tex]
Combine the data
[tex]3x + 4 = - 3x - 4[/tex]
Add 3x to both sides.
[tex]6x + 4 = - 4[/tex]
Subtract 4 from both sides.
[tex]6x = - 8[/tex]
Divide by 6.
[tex]x = \frac{ - 8}{6} = - 1 \frac{1}{3} [/tex]
The answer is A. exactly 1 solution.
