Answer:
Infinite solutions
Step-by-step explanation:
Given is a system of equations.
-3x+y=10
-6x+2y=20
Equation I when multiplied by 2, gives as
-6x+2y =20 which is the same as equation 2 given.
This gives the two lines are not intersecting nor parallel. But the two lines are coincident with each other.
Hence each point on the line is solution.
Infinite solutions.
Let us try to solve and verify this
BY substitutition we have y = 3x+10, substitute in II
-6x+2(3x+10) =20
Or -6x+6x+20=20
20=20 Thus for any x, this becomes true.
Hence infinite solutions.
