The solutions to the given system of equations is (0, -6) and (1, -5)  
<h3>Simultaneous equations</h3>
From the question, we are to determine the solutions to the given system of equations 
The equations are 
x − y = 6 --------- (1)
y = x² −6 ---------- (2) 
From equation (1) 
x - y = 6 
∴ x = 6 + y ------- (3) 
Substitute into equation (2) 
y = x² −6
y = (6+y)² −6
y = (6+y)(6+y) -6
y = 36 + 6y + 6y +y² -6
y = 36 + 12y + y² - 6 
Simplifying
y² + 12y - y + 30 = 0
y² + 11y + 30 = 0
Solve quadratically 
y² + 11y + 30 = 0
y² + 6y + 5y + 30 = 0
y(y +6) +5 (y +6) = 0 
(y + 5)(y + 6) = 0 
y + 5 = 0 OR y + 6 = 0 
y = -5 OR y = -6 
Substitute the values of y into equation (3)
x = 6 + y 
When y = -5 
x = 6 + (-5) 
x = 6 -5 
x = 1 
When y = -6 
x = 6 + (-6) 
x = 6 -6 
x = 0 
∴ When x = 0, y = -6 and when x = 1, y = -5
Hence, the solutions to the given system of equations is (0, -6) and (1, -5)
