Help!!! Linear Equations
{2x+3y=13
{15x-3y+21

Question

anonymous · Answer

what are you trying to find? the solution set?

anonymous · Answer

x=-8/17
y=79/17

anonymous · Answer

ugly solution set

anonymous · Answer

The instructions say: Use the Elimination Method to solve each system of linear equations.

chriss · Answer

add the bottom to the top and you get 17x=34
solve for x and you get 2
then sub 2 into one of the original equations to get y which will get you 3

so x=2 and y=3

anonymous · Answer

it wouldn't be that hard to solve by hand since your y's are already set up

anonymous · Answer

15*2+-3*3=-21?


unless that plus sign is supposed to be an equal sign

myininaya · Answer

+== i believe

anonymous · Answer

depending on whether that is a plus or an equal sign lol

chriss · Answer

I didn't see that, but I do think the + is suposed to be an =

anonymous · Answer

wow party on this thread?

myininaya · Answer

we can use the operations anyway we want as long as we define those operations

chriss · Answer

If it's a system of equations set up to be an easy elimination problem then =21 makes sense :P

anonymous · Answer

LOL

anonymous · Answer

it'd be easy still if it was a plus sign also it'd just be

15x-3y=-21

myininaya · Answer

richellea which is it lol 
you know you don't have an equal sign in your second line right?

anonymous · Answer

either way we are both correct he can distinguish between the two answers XD

anonymous · Answer

Yes there is an equal sign.
