2x = -4x = -2
10x - 8 = 010x = 8x = 0.8
2x + 6 = 02x = -6x = -3
-4x - 7 = 0-4x = 7x = -1.75
Therefore, the solutions are x = -2, x = 0.8, x = -3, x = -1.75.
2x = -4
x = -2
10x - 8 = 0
10x = 8
x = 0.8
2x + 6 = 0
2x = -6
x = -3
-4x - 7 = 0
-4x = 7
x = -1.75
Therefore, the solutions are x = -2, x = 0.8, x = -3, x = -1.75.
