Answer:
y=-6 and x=0
Step-by-step explanation:
-4x -2y = -12
4x + 8y = -24
(add the equations)
6y = -36
-36/6 = -6
y=-6
(Add y value in any of the equations)
-4x-2(6) = -12
-4x-12=-12
-4x=0
x=0
The square of a positive integer added to 4 times the integer is 437..
x2 + 4x = 437
I chose to do this by completing the square..
x2+4x+4 = 437 + 4
(x+2)2 = 441
Take square root of both sides
x+2 = ±√441
x = -2 ± 21
x = -23 or x = 19
x = 19
