+129838 (A) 6x+4x-6=24+9x simplify
10x - 6 = 24 + 9x add 6 to both sides, subtract 9x from each side
x = 30 is trhe only solution neither
(B) 25-4x= 15-3x+10-x simplify
25 - 4x = 25 - 4x identity ....this is true for all x ...it has infinite solutions
(C) 4x+8= 2x+7+2x-20 simplify
4x + 8 = 4x - 13 contradiction.......we can't add unlike quantites to equals and get equals.....hence, no solution
