    6 - a = 1/3(9a - 18) -- distribute through the parenthesis 6 - a = 3a - 6 -- subtract 3a from both sides 6 - a - 3a = -6 -- subtract 6 from both sides -a - 3a = -6 - 6 -- combine terms -4a = -12 a = -12/-4 a = 3 no need to go further....when it ends in " a = something " or " x = something " then there is only 1 solution. So the answer is A

    4x + 2(x - 3) = 8x + 12 4x + 2x - 6 = 8x + 12 6x - 6 = 8x + 12 this will end up with only 1 solution

    4(2x - 3) - 4x = 8x - 12 - 4x = 4x - 12...it is A

    wait...I read it wrong...give me a sec A is not 1 solution...it is infinite solutions...so not A 4x - 12 = 3x - 4 -- one solution for B 4x - 12 = 3(2x - 6) 4x - 12 = 6x - 18 --- one solution for C 4x - 12 = 4(x - 5) 4x - 12 = 4x - 20 --- 0 solutions for this one...so it is not D answers are : B and C

    identity equation is where there is infinite solutions. contradiction equation means there is no solutions. 8x + 24 = 2(4x + 12) 8x + 24 = 8x + 24 --- infinite solutions....identity 5x + 18 - x = 2(2x + 8) 4x + 18 = 4x + 16 .... no solution....contradictory 7(3x - 2) = 20x - 13 21x - 14 = 20x - 13 -- one solution......neither 3x + 2(x - 10) = 5(x - 4) 3x + 2x - 20 = 5x - 20 5x - 20 = 5x - 20.....infinite solutions....identity
