What is the solution set of this system of equations?
y = x2 - 3x - 4
x = y + 8
Solution:
Given y = x2 - 3x - 4 --- (a)
x = y + 8 --- (b)
By solving the linear equations (a) and (b) by substitution method
We get x - 8 = x2 - 3x - 4
x2 - 3x - 4 - x + 8 = 0
x2 - 4x + 4 = 0
(x - 2)2 = 0
x = 2
Put x = 2 in eq(b),
We get, 2 = y + 8
y = 2 - 8
y = -6
What is the solution set of this system of equations?
y = x2 - 3x - 4
x = y + 8
Summary:
The solution set of this system of equations y = x2 - 3x - 4 and x = y + 8 are (2, -6).
