Answer:
3x-5=9x+4x=1
We move all terms to the left:
3x-5-(9x+4x)=0
We add all the numbers together, and all the variables
3x-(+13x)-5=0
We get rid of parentheses
3x-13x-5=0
We add all the numbers together, and all the variables
-10x-5=0
We move all terms containing x to the left, all other terms to the right
-10x=5
x=5/-10
x=-1/2
