solution: y = 0 x = -1
(x, y) = (-6, 0)
y = x2 + x = 0 x (X + 1) = 0 x = 0 is one solution x = -1 is the other
y = 0x = y + 2plug 0 in for yx = 0 + 2x = 2
0
solution: y = 0 x = -1
(x, y) = (-6, 0)
y = x2 + x = 0 x (X + 1) = 0 x = 0 is one solution x = -1 is the other
y = 0x = y + 2plug 0 in for yx = 0 + 2x = 2
0
x = 0 & y = -3
x = 0 and y = 4
y = 0 and x = 8.
0
y = x - 1 y = -x + 1 (add both the equations) 2y = 0 y = 0 when y = 0, x = 1 So that the only solution is the intersection point of the lines, (1, 0).
x-2y=0 x=2y The solution set is the set of all (x,y) such that x=2y
The solution is:- x = 0 and y = 5
