What is the solution of the system of equations? 2x+2y+3z=-6 3x+5y+4z=3 2x+3y+4z=-10

Bismuth-210 is an isotope that radioactively decays by about 13% each day, meaning 13% of the remaining bismuth-210 transforms into another atom (polonium-210 in this case) each day. if you begin with 233 mg of bismuth-210, how much remains after 8 days?
