Answer: the x coordinate of the solution is 1
Step-by-step explanation:
y = x^2 + 1 - - - - - - 1
y – 1 = x - - - - -2
From equation 2 , y = x + 1
Substituting y = x + 1 into equation 1, it becomes
x + 1 = x^2 + 1
x^2 + 1 - x - 1 = 0
x^2 - x - 1 + 1 = 0
x^2 - x = 0
Let x be on the right hand side of the equation and x^2 remains on the left hand side of the equation. It becomes
x^2 = x
Dividing the left hand side of the equation and the right hand side of the equation by x, it becomes
x^2/x = x/x
x = 1
Therefore, x = 1
