Expand.
\[0.4x-0.24=x+0.4\]
Subtract \(0.4x\) from both sides.
\[-0.24=x+0.4-0.4x\]
Simplify \(x+0.4-0.4x\) to \(0.6x+0.4\).
\[-0.24=0.6x+0.4\]
Subtract \(0.4\) from both sides.
\[-0.24-0.4=0.6x\]
Simplify \(-0.24-0.4\) to \(-0.64\).
\[-0.64=0.6x\]
Divide both sides by \(0.6\).
\[-\frac{0.64}{0.6}=x\]
Simplify \(\frac{0.64}{0.6}\) to \(1.066667\).
\[-1.066667=x\]
Switch sides.
\[x=-1.066667\]
x=-1.0666666666667
