Answer is infinite solutions
Step-by-step explanation
These are all the same lines so there are infinite many solutions
Eq#2 and 3 can be reduced to be the same as equation 1
4x - 6y + 2z =4
Divide all by 2
2x - 3y + z = 2 same as equation 1
6x -9y + 3z = 6
Divide all by 3
2x -3y + z = 2 same as equation 1
