Answer:
14
Explanation:
Let's take it step-by-step
7x-1+6x-1=180
We move all terms to the left:
7x-1+6x-1-(180)=0
We add all the numbers together, and all the variables
13x-182=0
We move all terms containing x to the left, and all other terms to the right
13x=182
x=182/13
x=14
So remember, we move all terms to the left. We add all the numbers together, and all the variables. And we move all terms containing x to the left, and all other terms to the right.
