i need help with solving
equations and formulas such as Thanks 

Hi Lonnie, I find that it helps to think of an equation as a scale. One that you might find in the physics lab, with a pan on each sides. In your case you have 3x+b on one side and 6x on the other. The equal sign means that they balance. The object is to perform "legitimate" operations and end with just x on one side and something not involving x on the other side. What are "legitimate" operations? I can add of or subtract weights from either side as long as I maintain the balance. That means I can add the same amount to both sides or subtract the same amount from both sides. I can also multiply both sides by the same amount or divide both sides by the same amount since this will also maintain the balance. Your equation is
I want to arrive with an equation that has only x on the right side so I need to eliminate the 3x from the left side. I do this by adding 3x to both sides. This maintains the balance and gives me
Simplifying I get
I am almost there. I want x on the right side and I have 9x, hence I am going to divide both sides by 9. This gives
Which is
Thus I know that x is ^{b}/_{9}. Penny
