Step-by-step explanation:

Tip: Try using words that might appear on the page you’re looking for. For example, "cake recipes" instead of "how to make a cake."

12+3.4x-5.4x=x

We move all terms to the left:

12+3.4x-5.4x-(x)=0

We add all the numbers together, and all the variables

-3x+12=0

We move all terms containing x to the left, all other terms to the right

-3x=-12

x=-12/-3

x=+4
