Please help :)
x+y=19 11(x)+13(y)=209 solve for x and y
is there a shorter version to do this that' should be a lot of work
I solve for it and I always get like 19 or some decimal o-o
It just doesn't seem right!
i think i got a decimal also
(1)x11: 11x+11y = 209 ---(3) (2)-(3): 2y=0 --> y=0 ---(4) (4)>(1): x=19 ---(5)
x = 19?
So there are no non members? o_O
OMG SO I WAS RIGHT THE WHOLE TIME
It just seemed so weird, why would they have it like that o-o
Never doubt yourself :p
I'm in an Algebra honors class, I get everything else except these type of problems v-v
So when something that weird shows up, I'm unsure if it's correct or not
I'm at a level equivalent to grade 9
I will be at a level equivalent to grade 10 in september
Like how old are you?
how are you that smart
People work really hard to get to that level of intellect!
good job man
Only confusing thing know is me wondering why he did those: ---3 ---4 ---5 o_O
Is that some sort of way to keep your equation organized or something
So that I can refer to the equations
yeah :P So all that stuff like (4) > 1: is a system you developed for when you answer questions on here? Wow...interesting
I usually write subst (4) into (1) in exams
But I'm too lazy
So that's a yes
Arent we all lazy in our own special little ways? haha :P
I suppose so ;)
