Answer:
You already have what you are going to substitute, just put the y values from the first equation into the second! Like this:
6x - 5(-2x - 9) = -19
Multiply it out:
6x +10x +45 = -19
Add like terms + simplify:
16x + 45 = -19
16x = -64
x = -4
take that x and put it back into the first equation!!
y = -2(-4) -9
y= 8-9
y= -1
so... your answer is (-4, -1)
hope this helps!
