$x = \frac{31}{42}$ $x=31/42$

Explanation:

$subtract 1.4 from both sides$ $"subtract 1.4 from both sides"$

$- 4.2 x = - 1.7 - 1.4 = - 3.1$ $-4.2x=-1.7-1.4=-3.1$

$divide both sides by - 4.2$ $"divide both sides by "-4.2$

$x = \frac{- 3.1}{- 4.2} = \frac{31}{42} \leftarrow exact solution$ $x=(-3.1)/(-4.2)=31/42larrcolor(red)"exact solution"$
