How do you solve the system #-6x - 2y = -5 # and #-12x - 4y = -10#?
There are infinite solutions
Both these equations represent the same line. How you ask? Multiply the first equation by 2 and you get the same equation.
This means that the lines completely coincide and they are on each ther, This implies that all points on one line is on the other line as well
Thus there are infinite solutions
