the answer is B.(5,-19) because x=5 and y= -19
so -5(5)+6=-19
and -3(5)-4=-19

to find this use substitution. substitute -3x-4 in for Y

now you have
-5x + 6 = -3x -4   add 5x and 4 to both sides

10= 2x   divide by two on both sides
x=5
If you place 5 in where x is, you will get y= -19

The answer is B
