I want to help you find the answer for the question that you are asking for but you just said find the length of the missing side and there is no numbers or picture for me to help you please upload a picture with the question so that I can help you....
A) x + 4y = -15
B) -2x -8y = 30
Multiplying A) by 2
A) 2x + 8y = -30
This has NO solution because A) and B) are actually the same equation.
Equation B = Equation A times minus 2.
