Answer:
X=+17
Explanation:
We move all terms to the left:
19+4x-20-(6x-35)=0
We add all the numbers together, and all the variables
4x-(6x-35)-1=0
We get rid of parentheses
4x-6x+35-1=0
We add all the numbers together, and all the variables
-2x+34=0
We move all terms containing x to the left, all other terms to the right
-2x=-34
x=-34/-2
x=+17
