Simplify by combining the like terms.
x + 5 - 2x + 3 = 8 - x
7 - 3x - 1 = 6 - 3x
8 - x = 6 - 3x
8 = 6 - 2x
2 = -2x
x = -1
Check by plugging -1 into the original equation.
-1 + 5 - (-2) + 3 = 7 - (-3) - 1
9 = 9
It checks.

When solving the equation 4x equals 16 would you divide both sides of the equation by 4 or by 16 explain?
by 4. You do this because you want to find out what x equals. If you divide by 16, you find out what 1/4X equals, and that isn't much good to you. x=4 is the answer.

What reduces an equation that has two variables to an equation that has one variable. It is then possible to find the solution for this variable.?
substitution
How do you find x in the equation 4x equals 1 over 16?
As usual when solving equations, you need to "isolate" the variable, in this case, the variable "x". 4x means 4 times x; if you divide both sides of the equation (the left side and the right side) by 4, you will have achieved this.
What is a equation with Variable?
An equation with a variable is a math problem with a missing number that you have to find out using some specific steps that you are taught. Example: 4+n=5. If you want to find out what the variable is, you have to do the OPPOSITE OPPERATION and find it out. So I would take the answer, and do the opposite operation and then the answer is the variable. Of course there are MUCH harder variable equations. :D
Explain how to find restrictions on the variable in a rational equation?

How do you solve the equation 720 equals 2a x 3b x 5c?
I have the feeling that you were looking to find a value for each variable in this equation. Unfortunately you can only solve for each variable in terms of the other variables in this equation.
What does solve the equation mean?
Find values for the variable that satisfy the equation, that is if you replace those values for the variable into the original equation, the equation becomes a true statement.

What is the goal of solving an equation with one variable?
The goal is to find what value or values the variable may have, to make the equation true.
Is it possible to find three solutions of the equation x3 plus 2x2 plus 3x plus 6 equals 0 Explain why or why not?
The variable term, X^3, is a third order polynomial term and will render three solutions, though one of those may be zero.
