I have one suggestion however:
When you write 3/x-4 and you really mean 3/(x-4), be sure to use parentheses, otherwise, 3/x-4 may be mistakenly construed as (3/x)-4
Good work!

Treat this as an equality while solving

since you have equivalent fractions, cross multiply

distribute

subtract 2x from both sides

add 6 to both sides

since we did not multiply or divide by a negative number, put the < back in as is

You got the same answer. This is just one other way to solve the same problem.
