Nope. In this case, x would be equal to -2. Here's how you can work it out:
Given:
2x + 4 = 0
Subtract four from both sides of the equation:
2x + 4 - 4 = 0 - 4
2x = -4
Now divide both sides by two:
2x / 2 = -4 / 2
x = -2
x=0
x = 0
2x+52=0 =>2x= -52 =>x= -52/2 =>x= -26
2x = -7 - 8y
If -2x +14 = 0, -2x = -14, or x = 7.
-2x+16 = 0 -2x = -16 x = 8
4x2-2x = 0 2x(2x-1) = 0 x = 0 or x =1/2
Assuming that 4x2+2x = 0: 2x (2x+1) = 0 2x = 0 or 2x+1 = 0 x = 0 or -1/2
many solutions
y= -2x
2x + 2x + 146 + 26 = 172 4x + 172 = 172 4x = 0 x = 0
(2x + 3)(2x + 3)
