Q. \begin{cases}0.5(8w+2v)=3\8w=2-v+4w\end{cases}\Which of the following accurately describes all solutions to the system of equations shown?1)$v=11) \$v=1 and w=14w=\frac{1}{4}2)$v=42) \$v=4 and w=14w=\frac{1}{4}\(3) There are infinite solutions to the system.\(4) There are no solutions to the system.
  1. Simplify and solve: Simplify and solve the first equation:\newline0.5(8w+2v)=30.5(8w + 2v) = 3\newlineExpand the equation:\newline4w+v=34w + v = 3
  2. Expand the equation: Simplify and solve the second equation:\newline8w=2v+4w8w = 2 - v + 4w\newlineSubtract 4w4w from both sides:\newline4w=2v4w = 2 - v
  3. Simplify and solve: Substitute the expression for 4w4w from the second equation into the first equation:\newline4w+v=34w + v = 3\newline(2v)+v=3(2 - v) + v = 3\newline2=32 = 3
