Question

If you can...Solve the system of equations.

2x - 5y = 3
x - 3y = 1

Answer 1

multiply the 2nd equation by 2
what do u get ?

Answer 2

?

Answer 3

the co-efficient of 'x' in 1st equation is 2
but in 2nd equation it is 1

by multiplying the whole 2nd equation by 2, we are trying to make the same co-efficient for 'x'
so that we can subtract these equation, and 'x' would get eliminated!

Answer 4

alright here are the answer choices. (4, 1)

(5, 2)

(7, 2)

(9, 3)

Answer 5

sorry, i didn't ask for it.

here's your 2nd equation,
\(x - 3y = 1\)
now, multiply every term by 2
\(2(x - 3y) = 2\times1\)

can you simplify that ? (thats what i am asking)

Answer 6

I don't even know how to do this. That's why i'm here.

Answer 7

I am trying to make you learn how to do it, thats why i am here :)

i think you can try simplifying left side,
\(2(x-3y)\)
heard of distribution property ??? \(a(b+c)=ab+ac\)

Answer 8

ah can I learn tomorrow its almost 2:00 am I just need the answers at this point. ill be back tomorrow can we review then?

Answer 9

ofcourse! :)
just tag me when you come back ...

Answer 10
