Answer:
wasn't sure what you wanted us to answer, so I have the distance formula for you, and I worked it out.
Step-by-step explanation:
hope these help (:
But i really need a name of this book and authors :)
4(x-3)-(2x+5)=-3x-27
4*x - 4*3 - 2x - 5 = -3x - 27
4x - 12 - 2x - 5 = -3x - 27
2x - 17 = -3x - 27
2x + 3x = -27 + 17
5x = -10 / : 5
x = -2
