Work:
2x+5(6x+23)=-13
2x+30x+115=-13
32x=-128
x=-4
y=6(-4)+23
y=-24+23
y=-1
The answer is (-4,-1)
Hopefully this helps!

Answer:
77.78 mph
Step-by-step explanation:
[1] So we know that someone is driving 350 miles and it takes / took them 4 1/2 hours. I am going to change 4 1/2 to 4.5 for the sake of making it easier.
[2] Miles per hour, is, as it says, miles per hour. Aka,
(your time is almost always on the bottom / the y)
[3] So, that being said, to solve you will but 350 over 4.5 like this:
which calcuates to arounddd 77.78!
(I hope this is correct, I was slightly confused by the wording. Have a nice day!)
