Question

I am supposed to solve this by the elimination method 2x + 3y =1 and 4x + 6y =2 is there no soulution to this problem?

Answer 1

multiply the first equation with 2 u will get the second equation

Answer 2

2x + 3y = 1 --------(1)
4x + 6y = 2 --------(2)
Multiply (1) by 2 and subtract (2) from the resulting equation
2(2x + 3y = 1) gives 4x + 6y = 2 which is same as (2)
so their subtraction results in zero.

These two equations represent the same line and hence have infinite solutions

Answer 3

parallel lines that do not intersect for a solution .

Answer 4

@radar
both equations represent the same line and hence they have infinite solutions

Answer 5

divide the second eqn by 2 and u get the first eqn !!!!

Answer 6

y=-2/3 (x) +1/3

y=-2/3x + =1/3

You're right Harkirat, they are identities, same line.

Answer 7

if a1/a2 = b1/b2 = c1/c2
then the lines coincide and have infinitely many solutions

Answer 8

thx for the medal
can u pls kindly become my fan, i need some more.......
