Question

can somone helpme.ive been trying to do this but i havent understand how to
10x+5y=2250
x/10+y/5=400

Answer 1

first off multiply the second by 10 to get rid of the stupid decimal

Answer 2

now you can see plainly that the ratio of y to x is the same, so these are either the same line or two parallel lines

Answer 3

dang i meant
\[10x+5y=2250\]
\[2x+y=800\]

Answer 4

there that is better

Answer 5

so because the ratio is the same, two x for every one y in both of these, they have the same slope. so there is either no solution or they are the same line

Answer 6

if you multiply the second equation by 5 you get
\[10x+5y=2250\]
\[100x+5y=4000\] and now you can see that they are not the same line, they are parallel lines. so no solution to this system

Answer 7

oh okay thank you
