It depends on the equation, of course. Often you can open parentheses, and often this isn't necessary. Often you can use more than one method. Here is one example:2(x + 1) = 14
Here, you can open the parentheses and write the equation as:
2x + 2 = 14
However, you can just as well divide both sides of the equation by 2, to get rid of the 2 on the left, resulting in:
x + 1 = 7
Yes, when there are parenthesis in an equation, you have to use the distibutive property.
multiply the whole equation by the number in the denominator
Do you mean "equations involving exponential functions"? Yes,
because it tells you that you need to do distribute that number to all the other numbers. if you didnt use it your would come out with the wrong answer... not all the time but in most cases your answer will be incorrect if you do not use the distributive property
1/x=c+1/b, solve for x x=c+b/1
In the same way that you would solve equations because equivalent expressions are in effect equations
Equations can be tricky, and solving two step equations is an important step beyond solving equations in one step. Solving two-step equations will help introduce students to solving equations in multiple steps, a skill necessary in Algebra I and II. To solve these types of equations, we use additive and multiplicative inverses to isolate and solve for the variable. Solving Two Step Equations Involving Fractions This video explains how to solve two step equations involving fractions.

Do you mean "equations involving exponential functions"? Yes,
The absolute value of something is also the square root of the square of that something. This can be used to solve equations involving absolute values.
because it tells you that you need to do distribute that number to all the other numbers. if you didnt use it your would come out with the wrong answer... not all the time but in most cases your answer will be incorrect if you do not use the distributive property
Because this equation has four variables, it would require four unique equations involving only these four variables to solve.
1/x=c+1/b, solve for x x=c+b/1
It depends on the particular equation, of course. You can use several tricks, including eliminating things outside the parentheses, and using the distributive property. Here is one example: 2(x+3) = 10 Divide both sides by 2: x + 3 = 5. (The remainder should be easy to solve. Another soution, using the distributive property: 2(x+3) = 10 2x + 6 = 10 Again, I am assuming you know how to solve equations WITHOUT parentheses, so I won't give the full solution here.
You can use an abacus to add and subtract quantities of beads by moving the them around. This can in turn help to solve equations involving counting numbers.
