identify the point of intersection -2x-4y=1, 12y=-6x-3

Question

identify the solution(s) of the systems of equations, if any -2x-4y=1 and 12y=-6x-3.

 

Answer 1

The first equation is - 2x - 4y = 1    →(1)

The second equation is 12y = - 6x - 3  →(2)

Divide each side by 3 to (2).

4y = - 2 x - 1

Add 2x to each side.

2x + 4y = - 1

Divide each side by negative 1.

- 2x - 4y = 1.→(2)

So,the above two lines are equal lines.so,there is no solution.
