Identify Equations: First, let's identify the system of equations we need to solve:x2−6x+11=y,x=y+1We need to find the value of x that satisfies both equations.
Substitute and Solve: We can substitute the second equation into the first to solve for x. Substitute y from the second equation (x=y+1) into the first equation (x2−6x+11=y): x2−6x+11=x−1
Solve Quadratic Equation: Now, let's solve the resulting equation for x:x2−6x+11=x−1Move all terms to one side to set the equation to zero:x2−6x+11−x+1=0x2−7x+12=0
Factor and Solve: Factor the quadratic equation: (x−3)(x−4)=0
Check x=3: Set each factor equal to zero and solve for x:x−3=0 or x−4=0x=3 or x=4
Check x=4: We have two potential solutions for x: 3 and 4. We need to check which, if any, satisfy both original equations.First, check x=3:Substitute x=3 into the second equation (x=y+1):3=y+1y=2Now, substitute x=3 and y=2 into the first equation (x1):x2x3x4This is true, so x=3 is a solution.
Check x=4: We have two potential solutions for x: 3 and 4. We need to check which, if any, satisfy both original equations.First, check x=3:Substitute x=3 into the second equation (x=y+1):3=y+1y=2Now, substitute x=3 and y=2 into the first equation (x1):x2x3x4This is true, so x=3 is a solution.Next, check x=4:Substitute x=4 into the second equation (x=y+1):x930Now, substitute x=4 and 30 into the first equation (x1):343536This is also true, so x=4 is also a solution.
