Answer:
The solution is (-4,-8)because the point satisfies both equations.
Step-by-step explanation:
Line A: y = x − 4
Line B: y = 3x + 4
Substitute the value of y from Line A in Line B
[tex]x-4=3x+4[/tex]
[tex]-4-4=2x[/tex]
[tex]-8=2x[/tex]
[tex]-4=x[/tex]
Substitute the value of x in Line B to get value of y
[tex]y=3x+4[/tex]
[tex]y=3(-4)+4[/tex]
[tex]y=-12+4[/tex]
[tex]y=-8[/tex]
Thus the solution is (-4,-8)because the point satisfies both equations.
