Which ordered pair is a solution of the system ?
1 answer:
Hello!
Since we already see an equation that equals y (-2x-4), we can plug that equation into the first to solve for x.
x+4(-2x-4)=19
x-8x-16=19
-7x=35
x=-5
Now that we know the value of x, we will plug it into the second equation to solve for y.
y=-2(-5)-4
y=10=4
y=6
This gives us the answer below
The correct answer is A) (-5,6)
I hope this helps!

Answer:
The answer is D, 43
Step-by-step explanation:
If the pile gets bigger by 8 each week, and you want to find out how big the pile is after 3 weeks, then you have to multiply 8
by 3 to find out how much the pile increased by.
8 × 3 = 25
Now, you need to add this to your initial value to get the answer.
25 + 17
= 42
Now simplify.
43
