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: $10.3-6\times2.1=-2.3$
