2x + 3y = 1
y = 3x = 15

nnesha · Answer

there is 4 ways to do it 
elimination 
substitution 
matrices 
and graphing 
which one is easy for you ??

nnesha · Answer

and that suppose to be   y = 3x - 15 
or plus 15 ??? 
2nd equation

anonymous · Answer

i dont know... which one is easier??

anonymous · Answer

i would say elimination...

nnesha · Answer

well easy one is graphing 
then elimination
and then substitution( for this one you have to solve one of equation for either x or y then replace that into second equation like in this question. 2nd equation is already solved for y )

nnesha · Answer

do you know any thing about distributing  ??

anonymous · Answer

yes

nnesha · Answer

okay then lets do substitution

nnesha · Answer

you didn't tell me what is 2nd equation is it negative 15 or positive 15 ??

nnesha · Answer

bec there is two equal signs ^^^

anonymous · Answer

oh XD ooops! positive XD

nnesha · Answer

okay :) s0 |dw:1422244079565:dw|
replace y by 3x+15
