Question

Solve for x.

-5x + x + 9 = -4x + 12


a.Ø
b.{1/7}
c.{all reals}

Answer 1

\[6(x - 2) = 4\]\[(x - 2) = 4/6\]\[(x - 2) = 2/3\]\[x= 2/3+2=2 \frac{2}{3}\]

Answer 2

That does not make sense at all. This is the correct answer:
-5x+x+9=-4x+12 ---------> Combine variables on both sides.
-4x+9=-4x+12
+4x +4x ---------Both of the x's cancel
\[9\neq 12\]
