Solve the following system of equations. In other words, which  values for x and y make both equations true?

I'm assuming the two equations are as follows:
y = 5x
7x + 2y = -17

You can substitute 5x for y in the second equation since they are equivalent. Remember that whatever you do to one side you must do to the other as well.
7x + 2y = -17
7x + 2(5x) = -17
7x + 10x = -17
17x = -17
17x /17 = -17 /17
x = -1

Now we sub in the value we have for x to find y:
y = 5x
y = 5(-1)
y = -5

We now check that both answers are right by substituting them both into the second equation:
7x + 2y = -17
7(-1) + 2(-5) = -17
-7 + (-10) = -17
-17 = -17

And it looks like it works! So x = -1, and y = -5. Hope this helps! :)

PLEASE HELP if Suzy can drive 4/5 miles in a half hour how many miles can she drive in 1 hour FOR A TEST PLEASE ANSWER
kati45 [8]
Since you are trying to figure out how many miles she can drive in 1 hour and you already have half of that hour, all you would need to do is double that number. 
\frac{4}{5} × \frac{2}{1}= \frac{8}{5}

Now, all you would need to do is simplify the answer.
\frac{8}{5} = 1 \frac{3}{5} or 1.6

The answer would be, Suzy can drive 1 \frac{3}{5} or 1.6 miles in 1 hour. 

I hope this helps!
