Answer: The answer is x=2/3
Step-by-step explanation: This is the linear equation to solve it we have to take 6x to the other the sign will change to be negative then divide both sides by 3
3x=6x-2
3x-6x=-2
3x=-2
x=2/3
They are parallel since x and y are bottom and top
You are changing the sign on one so to keep an equilibrium you change the other sign too
9 ten thousandths is 0.0009, so it would be 9*10^-4
