Q. 3x+2y=4(xy6)6(y+x)=7x24 \begin{aligned} 3 x+2 y & =4(x-y-6) \\ 6(y+x) & =7 x-24 \end{aligned} \newlineWhich of the following accurately describes all solutions to the system of equations shown?\newlineChoose 11 answer:\newline(A) x=3 x=3 and y=1 y=-1 \newline(B) x=12 x=12 and y=2 y=-2 \newline(C) There are infinite solutions to the system.\newline(D) There are no solutions to the system.
  1. Expand and simplify the first equation: Expand the first equation to simplify it.\newline3x+2y=4(xy6)3x + 2y = 4(x - y - 6)\newline3x+2y=4x4y243x + 2y = 4x - 4y - 24\newline2y+4y=4x3x242y + 4y = 4x - 3x - 24\newline6y=x246y = x - 24
  2. Expand and simplify the second equation: Simplify the second equation.\newline6(y+x)=7x246(y + x) = 7x - 24\newline6y+6x=7x246y + 6x = 7x - 24\newline6y=7x6x246y = 7x - 6x - 24\newline6y=x246y = x - 24
  3. Compare two equations: Compare the two simplified equations.\newlineFrom Step 11: 6y=x246y = x - 24\newlineFrom Step 22: 6y=x246y = x - 24\newlineWe can see that both equations are identical, which means every solution to one equation is also a solution to the other.
  4. Final Solution: Determine the type of solution set.\newlineSince both equations are identical, there are infinitely many solutions to the system. Any value of xx and yy that satisfies one equation will satisfy the other.
