Question

Please help
2x+6y= 5
x+3y=2

Howmany solutions (x,y) are there to the system of equations above?

Answer 1

perhaps multiply equation 2 by a factor of 2 and see what you get

Answer 2

first:

multiply the second equation by 2 and post the result here...

Answer 3

we know whats up haha

Answer 4

what's up? the ceiling, then clouds, then the stratophere

Answer 5

these are parallel lines

Answer 6

I'd say, solve each equation for "y"
so you can see their slope

same slopes, no solutions since they're parallel
different slopes, one solution

Answer 7

@MrNood and @jdoe0001 its 2x+6y=4?

Answer 8

we would clearly see the troposphere before the stratosphere..hahaa

Answer 9

@chris00 and after that, some asteroids floating about, make sure you wear a helmet there though :P

Answer 10

ok - that's correct

so if you look at the first equation
2x + 6y=5

and your equivalent to the seconf
2x+6y=4

then you can see that they cannot BOTH be true for the same values of x and y

therefore there is no solution to th e'system'

the lines do not intersect

Answer 11

Okay thanks I remember now @MrNood :)

Answer 12

parallel and distinct lines
