Given that eight π₯ minus nine equals twenty-three, find the value of π₯ divided by two.

So the first thing that we need to do is we need to find what π₯ is equal to. So we will take our equation, eight π₯ minus nine equals twenty-three, and we will solve for π₯. So in order to solve for π₯, we first need to get rid of the minus nine.

The opposite of subtracting nine would be to add nine. Thatβs how we will get rid of the minus nine. So we need to add nine to both sides of the equation.

On the left-hand side of the equation, the nine is cancelled. And on the right-hand side of the equation, twenty-three plus nine is equal to thirty-two. So now in order to isolate π₯ to get it by itself, eight is being multiplied to π₯. So to get rid of eight, we must divide by eight. We have to do that to both sides of the equation.

The eight is cancelled on the left-hand side of the equation. And on the right-hand side of the equation, thirty-two divided by eight is equal to four, so π₯ is equal to four.

Now it wants us to find the value of π₯ divided by two. So letβs replace π₯ with four. And four divided by two is equal to two, so the value of π₯ over two or π₯ divided by two is equal to two.
