x=17

Step-by-step explanation:

To solve the equation, we want to find out what x is. In order to do this, we have to get x by itself. Perform the opposite of what is being done to the equation. Keep in mind, everything done to one side, has to be done to the other.

x/2=8.5

x is being divided by 2. The opposite of division is multiplication. Multiply both sides by 2.

2*x/2=8.5*2

x=8.5*2

x=17

To check the solution, substitute 17 in for x in the original equation.

Original equation: x/2=8.5

Substitute 17 in for x: 17/2=8.5

17/2=8.5

8.5=8.5

This is true, so we know that x is equal to 17.
