i) 8(x-3) - (6-2x) = 2(x+2) - 5(5-x)
= (8x-24) - (6-2x) = (2x+4) - (25-5x)
= 8x-24-6+2x = 2x+4-25+5x
= 8x+2x-24-6 = 2x+5x+4-25
= 10x-30 = 7x-21
= 10x-7x = -21+30
= 3x = 9
= x = 9/3
= x = 3
ii) 3(n-4) + 2(4n-5) = 5(n+2)+16
= (3n-12) + (8n-10) = (5n+10)+16
= 3n-12+8n-10 = 5n+10+16
= 3n+8n-12-10 = 5n+26
= 11n-22 = 5n+26
= 11n-5n = 26+22
= 6n = 48
= n = 48/6
= n = 8
