Q. 4p2t=6 4 p-2 t=6 \newline8p+6t=12+2t 8 p+6 t=12+2 t \newlineWhich of the following accurately describes all solutions to the system of equations shown?\newlineChoose 11 answer:\newline(A) p=32 p=\frac{3}{2} and t=0 t=0 \newline(B) p=3 p=3 and t=3 t=3 \newline(C) There are infinite solutions to the system.\newline(D) There are no solutions to the system.
  1. Write down equations: Write down the system of equations.\newlineWe have the following system of equations:\newline4p2t=64p - 2t = 6\newline8p+6t=12+2t8p + 6t = 12 + 2t
  2. Simplify second equation: Simplify the second equation by subtracting 2t2t from both sides.\newline8p+6t2t=12+2t2t8p + 6t - 2t = 12 + 2t - 2t\newline8p+4t=128p + 4t = 12
  3. Compare coefficients: Compare the coefficients of the simplified system of equations.\newlineWe now have:\newline4p2t=64p - 2t = 6\newline8p+4t=128p + 4t = 12\newlineNotice that the second equation is exactly twice the first equation.
  4. Determine solution type: Determine if the system has one solution, no solution, or infinitely many solutions.\newlineSince the second equation is a multiple of the first, the two equations are dependent, and the system has infinitely many solutions.
