I got $x = \frac{17}{5} = 3.4$ $x=17/5=3.4$

Explanation:

We can write it as:
$\frac{5}{10} x + \frac{42}{10} = \frac{59}{10}$ $5/10x+42/10=59/10$
Cancel all the $10$ $10$ and we can solve:
$5 x + 42 = 59$ $5x+42=59$
$5 x = 59 - 42$ $5x=59-42$
$5 x = 17$ $5x=17$
$x = \frac{17}{5} = 3.4$ $x=17/5=3.4$
