(2x)-4 = (3x)-8
2-4 * x-4 = 3-8 * x-8
1/24 * 1/x4 = 1/38 * 1/x8
(1/24) / (1/38) = (1/x8) / (1/x4)
(1/24) * (38) = 1/x8 * x4
38 / 24 = x4-8
38 / 24 = x-4
38 / 24 = 1/x4
38 * x4 = 24
x4 = (24/38)
I don't know how to write it here but then I took fourth roots of both sides that gave me the answer 2/9 = 0.222...
However, the correct answer is supposed to be 0 or 0.75. I know there are other ways I could go about getting the right answer, but I really wish to understand what am I doing wrong above. Your help would be deeply, sincerely appreciated. Regards, a (GRE) Prepper.
