Answer
$x=2.1$
Work Step by Step
$10.3-6x=-2.3$
Step 1: is not needed since there are no fractions.
Step 2: is not needed since there are no parentheses.
Step 3: is not needed.
Step 4: the equation is linear.
Step 5:
$10.3-6x-10.3=-2.3-10.3$ (Add 4.1 to both sides)
$-6x=-12.6$
Step 6: $\frac{-6x}{-6}=\frac{-12.6}{-6}$ Divide both sides by -6.
$x=2.1$
Final Step: check:
$10.3-6\times2.1=-2.3$
