Full solution

Q. x26x+11=yx=y+1 \begin{array}{c}x^{2}-6 x+11=y \\ x=y+1\end{array}
  1. Identify Equations: First, let's identify the system of equations we need to solve:\newlinex26x+11=y,{x^{2}-6x+11=y},\newlinex=y+1{x=y+1}\newlineWe need to find the value of xx that satisfies both equations.
  2. Substitute and Solve: We can substitute the second equation into the first to solve for xx. Substitute yy from the second equation (x=y+1x = y + 1) into the first equation (x26x+11=yx^2 - 6x + 11 = y): x26x+11=x1x^2 - 6x + 11 = x - 1
  3. Solve Quadratic Equation: Now, let's solve the resulting equation for xx:x26x+11=x1x^2 - 6x + 11 = x - 1Move all terms to one side to set the equation to zero:x26x+11x+1=0x^2 - 6x + 11 - x + 1 = 0x27x+12=0x^2 - 7x + 12 = 0
  4. Factor and Solve: Factor the quadratic equation: \newline(x3)(x4)=0(x - 3)(x - 4) = 0
  5. Check x=3x = 3: Set each factor equal to zero and solve for xx:x3=0x - 3 = 0 or x4=0x - 4 = 0x=3x = 3 or x=4x = 4
  6. Check x=4x = 4: We have two potential solutions for xx: 33 and 44. We need to check which, if any, satisfy both original equations.\newlineFirst, check x=3x = 3:\newlineSubstitute x=3x = 3 into the second equation (x=y+1x = y + 1):\newline3=y+13 = y + 1\newliney=2y = 2\newlineNow, substitute x=3x = 3 and y=2y = 2 into the first equation (xx11):\newlinexx22\newlinexx33\newlinexx44\newlineThis is true, so x=3x = 3 is a solution.
  7. Check x=4x = 4: We have two potential solutions for xx: 33 and 44. We need to check which, if any, satisfy both original equations.\newlineFirst, check x=3x = 3:\newlineSubstitute x=3x = 3 into the second equation (x=y+1x = y + 1):\newline3=y+13 = y + 1\newliney=2y = 2\newlineNow, substitute x=3x = 3 and y=2y = 2 into the first equation (xx11):\newlinexx22\newlinexx33\newlinexx44\newlineThis is true, so x=3x = 3 is a solution.Next, check x=4x = 4:\newlineSubstitute x=4x = 4 into the second equation (x=y+1x = y + 1):\newlinexx99\newline3300\newlineNow, substitute x=4x = 4 and 3300 into the first equation (xx11):\newline3344\newline3355\newline3366\newlineThis is also true, so x=4x = 4 is also a solution.
