how do i work this out

80=10x

divide each side by ten.

To solve the equation 80 = 10x, you can isolate the variable x by performing the same operation on both sides of the equation. In this case, you want to divide both sides of the equation by 10, so the equation becomes:

80/10 = (10x)/10

On the left side, 80 divided by 10 is equal to 8:

8 = x

Therefore, x is equal to 8.
