Q. 2x1=y3x1=y \begin{array}{l} 2 x-1=y \\ 3 x-1=y \end{array} \newlineConsider the given system of equations. Which of the following statements about this system is true?\newlineChoose 11 answer:\newline(A) There is only one (x,y) (x, y) solution and y y is positive.\newline(B) There is only one (x,y) (x, y) solution and y y is negative.\newline(C) There are infinitely many (x,y) (x, y) solutions.\newline(D) There are no (x,y) (x, y) solutions.
  1. Analyze System of Equations: Analyze the given system of equations.\newlineWe have the system:\newline2x1=y2x - 1 = y\newline3x1=y3x - 1 = y\newlineWe need to determine the nature of the solutions to this system.
  2. Compare Equations: Compare the two equations.\newlineBoth equations are equal to yy, so we can set them equal to each other:\newline2x1=3x12x - 1 = 3x - 1
  3. Solve for x: Solve for x.\newlineSubtract 2x2x from both sides to get:\newline1=x1-1 = x - 1\newlineNow, add 11 to both sides to find the value of xx:\newline0=x0 = x
  4. Substitute for y: Substitute xx back into one of the original equations to find yy. Using the first equation: 2x1=y2x - 1 = y 2(0)1=y2(0) - 1 = y y=1y = -1
  5. Conclude Solution: Conclude the nature of the solution.\newlineSince we found a single solution for xx and yy, there is only one (x,y)(x,y) solution. The value of yy is negative.
