If: 2x+y = 0 and x+y = -4
Then: x = 4 and y = -8
Possible steps:
2x + y = 0
x + y = -4
Subtract the two equations:
x = 4
Plug x back in to one equation and solve for y:
4 + y = -4
y = -8

-2x plus 14 equals 0?
If -2x +14 = 0, -2x = -14, or x = 7.
-2x plus 16 equals 0?
-2x+16 = 0 -2x = -16 x = 8
What are the points of intersection of the parabolas y equals x squared -2x plus 4 and y equals 2x squared -4x plus 4?
If: y = x^2 -2x +4 and y = 2x^2 -4x +4 Then: 2x^2 -4x +4 = x^2 -2x +4 Transposing terms: x^2 -2x = 0 Factorizing: (x-2)(x+0) => x = 2 or x = 0 Therefore by substitution points of intersect are at: (2, 4) and (0, 4)
