Solve each system by substitution
y=5x-10 y=3x+8
Is it like this?
5x-10=3x+8
+10 +10

you can always replace 9 for x to check
Your kidding? Yes its 9.
and its right
Reminds me of my girlfriend doing some damn ACT math problem, got all the way through it, honestly thought she knew the answer, said answer was 4. Looked it up in the back of the book, it was like ac-23b-sad-12kasd/sdla1232 shit. xD
Btw thats one whole problem right there.. >>
that actually looks like a slope intercept/graphing problem
No shit it's one problem...Quote:

x=9, yes. But, what does y =?
y=35
didnt notice that
Y= 5(9)-10
y=45-10
y=35
Tada...........
Solution is not only 9, and it isn't only 35. Put it in a coordinate.
Lol what? Unless it asked for a specific answer, x=9, y=35 should be a perfectly acceptable answer.Quote:

Depends how advanced your class is... x=9, y=35 is acceptable... (9,35) is just more exact or whatever... Hate math.Quote:

Lmao. I've been in some pretty advanced math classes, and for such a simple question x=9, y=35 is perfectly acceptable :pQuote:
