Answer:

B) {0}

Explanation:


8 + 4p = 8(1 + 8p) + 8p\\\\\mathrm{Expand}\:8\left(1+8p\right):\quad 8+64p\\8+4p=8+64p+8p\\\\\mathrm{Add\:similar\:elements:}\:64p+8p=72p\\8+4p=8+72p\\\\\mathrm{Subtract\:}8\mathrm{\:from\:both\:sides}\\8+4p-8=8+72p-8\\\\Simplify\\4p=72p\\\\\mathrm{Subtract\:}72p\mathrm{\:from\:both\:sides}\\4p-72p=72p-72p\\\\Simplify\\-68p=0\\\\\mathrm{Divide\:both\:sides\:by\:}-68\\(-68p)/(-68)=(0)/(-68)\\\\Simplify\\p=0
