Question

a) 2x – 5 + 3x + 1 = 3x – 2 b) x + 7 = 12x – 3 – 8x + 1 c) 6x – 1 + x = 4 – 5x + 3 d) x + 2x + 3x – 5 = 4x – 9 e) 5x + 4 – 6x = 7 – x – 3 f ) 4x + 2 + 7x = 10x + 3 + x

Answer 1

a) 2x – 5 + 3x + 1 = 3x – 2 b) x + 7 = 12x – 3 – 8x + 1 c) 6x – 1 + x = 4 – 5x + 3 d) x + 2x + 3x – 5 = 4x – 9 e) 5x + 4 – 6x = 7 – x – 3 f ) 4x + 2 + 7x = 10x + 3 + x
