x = 0
2y + 3x = 0 2y + -3 = 0 2y = 0 + 3 , 2y = 3 y = 3/2 y = 1.5 x = -1
True because in both equations x = 0 or x = -4
x2 + 3x - 10 = (x + 5)(x - 2) ⇒ x = -5 or 2
3x + 8 = 8 Therefore, 3x = 0 x = 0/3 x = 0
x = 0
x = 0
2y + 3x = 0 2y + -3 = 0 2y = 0 + 3 , 2y = 3 y = 3/2 y = 1.5 x = -1
True because in both equations x = 0 or x = -4
X2 - 3X - 4 = 0factored(X + 1)(X - 4)----------------X = - 1X = 4-------------------(- 1, 0) and (4, 0)================solution set of X interception points
x2 + 3x - 10 = (x + 5)(x - 2) ⇒ x = -5 or 2
3x2 - 19x - 14 = 0 3x2 - 21x + 2x - 14 = 0 3x(x - 7) + 2(x - 7) = 0 (x - 7)(3x + 2) = 0 x - 7 = 0 or 3x + 2 = 0 x = 7 or x = -2/3
3x + 8 = 8 Therefore, 3x = 0 x = 0/3 x = 0

If 3X-27= 0 then X=9
3x2 - 2x - 5 = (3x - 5)(x + 1) = 0 gives a solution of x = 5/3 or -1. Was that what you wanted?
3x2-4x-15 = 0 (3x+5)(x-3) = 0 x = -5/3 or x = 3
