First equation:2^2 - x = 164 - x = 16-x = 12x = -12
Second equation:4^1 - 2x = 644 - 2x = 64-2x = 60x = -30
Third equation:2^1 - x = 82 - x = 8-x = 6x = -6
Therefore, x = -12, -30, -6.
First equation:
2^2 - x = 16
4 - x = 16
-x = 12
x = -12
Second equation:
4^1 - 2x = 64
4 - 2x = 64
-2x = 60
x = -30
Third equation:
2^1 - x = 8
2 - x = 8
-x = 6
x = -6
Therefore, x = -12, -30, -6.
