What is the solution to the system of equation

3x-6y=-12

x-2y=-8

(a) Use substitution method to justify the given system of equation has no solution?

(b) what do you know about the two in the system of equation?

No solution

The lines are parallel

Step-by-step explanation:

To solve, use one equation and isolate x. Then substitute x into an equation.

x = - 8 + 2y will be substitute 3x - 6y = - 12.

3 (-8 + 2y) - 6y = - 12

-24 + 6y - 6y = - 12

-24 = - 12

This is a false statement. The variable was eliminated. There is no solution. This means the lines are parallel.
