#x = 3/5# or #0.6#

Explanation:

#5x + 7 = 10#

You need to subtract seven from both sides.

#5x + 7 - 7 = 10 - 7#

The two sevens on the left side cancel out and if you subtract seven from ten then you are left with this:

#5x = 3#

You then need to divide both sides by five so that the five on the left side becomes a one (which you don't need to write), and divide the three on the right side by five as well.

So therefore,

#x = 3/5 = 0.6#
