iii) \\ 8(x - 3) - (6 - 2x) = 2(x + 2) - 5(5 - x) \\ 8x - 24 - 6 + 24 = 2x + 4 - 25 + 5x \\ 8x - 24 - 6 = 4 - 25 + 5x \\ 8x - 30 =  - 21 + 5x \\ 8x - 5x =  - 21 + 30 \\ 3x = 9 \\ x =  \frac{ \cancel9 }{  \cancel3}  = 3

(iv) \\ 3(x - 4) + 2(4x - 5) = 5( x + 2) + 16 \\ 3x - 12 + 8x - 10 = 5x + 10 + 16 \\ 11x - 22 = 5x + 26 \\ 11x - 5x = 26 + 22 \\ 6x  = 48 \\ x =  \frac{ \cancel{48}}{ \cancel6}  = 8
