Question

Does this system of equations have one solution, no solution, or an infinite number of solutions?
2x+3y=6
4x+6y=12

Answer 1

no solution

Answer 2

how do you get that

Answer 3

than multiply first by 2 and subtract first from second you will get 0 0 0

Answer 4

No solution

Answer 5

ok thx

Answer 6

yw

Answer 7

o ok i see

Answer 8

Also using the matrix inverse idea,the det of the coefficient matrix is zero hence no solution as this is non-homogeneous equations

Answer 9

The matrix \[\matrix{2&3&6\\4&6&12}\] is row irreducible and thus inconsistent, meaning there are no solutions to th esystem of equations
