A) 6x = 2x + 16 => 6x - 2x = 16 => 4x = 16 => x = 4
B) 2x - 5 = x + 1 => 2x - x = 1 + 5 => x = 6
C) 2x + 3 = x + 4 => 2x - x = 4 -3 => x = 1
D) 5x + 7 = 4x + 10 => 5x - 4x = 10 - 7 => x = 3
E) 4x - 10 = 2x + 2 => 4x - 2x = 2 + 10 => 2x = 12 => x = 6
F) 4x - 7 = 8x - 2 => 4x - 8x = -2 + 7 => -4x = 5 => x = -5/4
G) 2x + 1 = 4x - 7 => 2x - 4x = -7 - 1 => -2x = -8 => x = 4
B) 2x - 5 = x + 1 => 2x - x = 1 + 5 => x = 6
C) 2x + 3 = x + 4 => 2x - x = 4 -3 => x = 1
D) 5x + 7 = 4x + 10 => 5x - 4x = 10 - 7 => x = 3
E) 4x - 10 = 2x + 2 => 4x - 2x = 2 + 10 => 2x = 12 => x = 6
F) 4x - 7 = 8x - 2 => 4x - 8x = -2 + 7 => -4x = 5 => x = -5/4
G) 2x + 1 = 4x - 7 => 2x - 4x = -7 - 1 => -2x = -8 => x = 4
