i get this
2x+(6/3-1/3x=-3 : NO! Multiply by 3 to get 6x + 6 - x = -9 (if you don't follow that, see your teacher!)
wrifalon said:2x+(6-x)/3=-3 The (6-x)/3 is a fraction (6-x) in the numerator and the 3 is on the bottom.
i get this
2x+(6/3-1/3x=-3
5/3x+6/3=-3
5/3x=-5<<<<< Right after this - you went wrong
(5/3)* x * (3/5) = -5 * (3/5) <<<<< multiply by 3/5 both sides - to isolate 'x'
x = - 3
You check your answer - by putting it into the original equation:
2x + (6 - x)/3 = 2*(-3) + [6 -(-3)]/3 = -6 + 9/3 = - 6 + 3 = -3 <<<< checks
