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
