Hi there,

please see below for solution steps :

________

We know what 3.25x is equal to. What do you think we should do to find x? Remember, we need opposite operations. Here x is multiplied by 3.25. What is the opposite of multiplying by 3.25? That's right, dividing by 3.25. But we can't ignore the golden rule of algebra - whatever you do to one side, you should do to the other. So we can only divide 3.25 by 3.25 if we divide the other side by 3.25 aswell.

Thus,


\boldsymbol{3.25x=8.125}\\\boldsymbol{x=2.5}

Hope the answer - & explanation - made sense,

happy studying !!
