sleepyhead314 · Answer

first isolate the x from the second equation by adding 3y to both sides of the second equation

anonymous · Answer

x=3y+1

anonymous · Answer

ummm are you there? or nah?

sleepyhead314 · Answer

sorry, I was afk for a while
yes x = 3y + 1 is correct :)
then plug that into x into the first equation
and solve for y

anonymous · Answer

How do i "plug it in"?

sleepyhead314 · Answer

plug in (3y+1) for x into  2x - 5y = 3

like  2(3y+1) - 5y = 3

anonymous · Answer

I am stupid how would i solve that?

sleepyhead314 · Answer

distribute the 2
then add like terms
then subtract 2 from both sides :)

anonymous · Answer

i am soooo confused............

sleepyhead314 · Answer

2(3y+1) - 5y = 3     distribute the 2
-> 6y + 2 - 5y = 3
do you see what I did there? :)

anonymous · Answer

yeahh

sleepyhead314 · Answer

then add like terms
6y + 2 - 5y = 3
6y - 5y + 2 = 3
so    y + 2 = 3

can you figure out what y equals from there? :P

anonymous · Answer

y=1

sleepyhead314 · Answer

yay! correct :) 
well technically you can get the answer from there :P
in the (x, y) format, when y=1  which answer choice do you think would match it?
