Will Fan and Medal for this simple question i don't understand :(

Question

anonymous · Answer

How can x + 2 = -3x + 11 be set up as a system of equations?

anonymous · Answer

no need to bribe a fan or medal...i'll make you understand

anonymous · Answer

Haha thanks a lot i was just trying to be nice not bribe but if you can help me understand it would be nice :)

anonymous · Answer

ok pls repeat the question?

anonymous · Answer

How can x + 2 = -3x + 11 be set up as a system of equations

anonymous · Answer

its very simple ...for setting up system of equations you need 2 variables ...is that understood?

anonymous · Answer

Yes

anonymous · Answer

then it is as simple as writing 
x+2 =y
-3x + 11 = y

anonymous · Answer

Wait, seriously?

anonymous · Answer

Oh

anonymous · Answer

You simply need to equate each expression to y so they both resemble a system of equations. Haha i feel so silly now. Thanks for the help :)

anonymous · Answer

thats it

anonymous · Answer

pretty silly idea though isn't it?

anonymous · Answer

Yeah it is

anonymous · Answer

when you go to higher class ....you may get problems of forming system of equations for a sencond order differential equation

anonymous · Answer

sorry *second

anonymous · Answer

Oh, do you mean like initial value problems and such?

anonymous · Answer

yes you can write a second order differential equations into two first order equations ...which would make the problems simpler

anonymous · Answer

ok did you understand that?

anonymous · Answer

yes thank you
