Abby solves the following equation and gets x = -\frac{2}{7} \frac{1}{3} (12x-6)-2x+28=-4(3x+9)+6\\
she gets it wrong. which step shows her error?






a) abby divided 14 and -4 incorrectly

b) abby combined like variable terms incorrectly

c) abby subtracted 26 from both sides incorrectly


\frac{1}{3} (12x-6)-2x+28=-4(3x+9)+6\\
4x-2-2x+28=-12x-36+6
2x+26=-12x-30
14x=-4
x=-\frac{2}{7}
