#x=4#

Explanation:

This is how to do it.

#5x-1=3x+7#

We separate terms with letters from terms with numbers only.
Add 1 to both sides of the equation to move all numbers to the right.
Also, Subtract 3x from both sides of the equation to move all terms with letters to the left.

#5x-1=3x+7#

#5x-1+1-3x=3x+7+1-3x#

Simplify

#5x-3x-1+1=3x-3x+7+1#

#2x=8#

divide both sides by 2

#(2x)/2=8/2#

#(cancel2x)/cancel2=8/2#

#x=4#

God bless...I hope the explanation is useful.
