You need to get x by itself on one side, so add 4 to both sides, then divide both sides by six.

You need to get a by itself, so add ten to both sides, then multiply both sides by 4.

You need x by itself, so either
a) add x to both sides then subtract 17 from both sides
or
b) subtract 5 from both sides, multiply both sides by negative one.

This is already solved, they are equal. If you want them to look the same, then choose either side and rewrite it to look like the other.
