Here is your equation:

You're looking for x. To find x alone, you have to remove everything on the same side of it. On that side you have:

The only thing you need to remove is +5(positive 5). To remove it, you have to do the opposite of it, which is -5(negative 5). It is also the same as subtracting 5. Subtract 5 from both sides:

x divided by 4 is equal to 2. To find x, you have to do the opposite of what's happening to it. x is being divided by 4. The opposite of that is multiplying by 4(times 4).

Multiply:

That means your answer is 8 ; x = 8
