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
4+2x-2x+1=13+6 Combine like terms. (4+1=5; 2x-2x=0; 13+6=19) 5=19 This problem has no solution.
