Q. Determine if the following system of equations has no solutions, infinitely many solutions or exactly one solution.\newline4x+y=46xy=6 \begin{array}{c} 4 x+y=4 \\ -6 x-y=-6 \end{array} \newlineOne Solution\newlineInfinitely Many Solutions\newlineNo Solutions
  1. Write Equations: Write down the system of equations to analyze. {4x+y=4 6xy=6\begin{cases} 4x+y=4 \ -6x-y=-6 \end{cases}
  2. Add and Eliminate yy: Attempt to solve the system by adding the two equations together to eliminate yy.\newlineAdding 4x+y=44x + y = 4 and 6xy=6-6x - y = -6 gives us:\newline4x+y6xy=464x + y - 6x - y = 4 - 6\newlineThis simplifies to:\newline2x=2-2x = -2
  3. Solve for x: Solve for x by dividing both sides of the equation by \(-2").\newline\(-2x / 2-2 = 2-2 / 2-2")\newlineThis gives us:\newlinex = \(1")
  4. Substitute xx into Equation: Substitute x=1x = 1 into one of the original equations to solve for yy. Using the first equation 4x+y=44x + y = 4: 4(1)+y=44(1) + y = 4 4+y=44 + y = 4 Subtract 44 from both sides to solve for yy: y=44y = 4 - 4 y=0y = 0
  5. Check Validity: Check the solution (x=1,y=0)(x = 1, y = 0) in the second equation to ensure it is valid.\newlineSubstitute x=1x = 1 and y=0y = 0 into 6xy=6-6x - y = -6:\newline6(1)0=6-6(1) - 0 = -6\newline6=6-6 = -6\newlineThe solution satisfies the second equation as well.
  6. Final Solution: Since we have found a single solution (x=1,y=0)(x = 1, y = 0) that satisfies both equations, the system has exactly one solution.
