When solving a system by multiplying and then adding or subtracting how do you decide whether to add or subtract?
When solving a system of equations by multiplying and then adding or subtracting, you decide whether to add or subtract based on the coefficients of the variables you want to eliminate. If the coefficients of one variable are opposites (e.g., +3 and -3), you would add the equations to eliminate that variable. Conversely, if the coefficients are the same (e.g., +3 and +3), you would subtract one equation from the other to eliminate the variable. The goal is to simplify the system and isolate one variable for easier solving.
What decisions do you need to make when you write an equation to represent a relatiship between variables?
You have to decide what the meaning of the equation will be.
How can you decide which variable to solve for first when you are solving a linear system by substitution?
When solving a linear system by substitution, it's often best to choose the variable that is easiest to isolate. Look for a variable with a coefficient of 1 or -1, as this will simplify the process of rearranging the equation. If both equations are equally complex, consider which equation seems simpler to manipulate or offers fewer terms. Additionally, choose the variable that appears most frequently, as this can make the substitution process more efficient.

Will the addition method and the substitution method for solving equations always give you the same answer?
The solution to an equation is the solution. It doesn't matter how you decide tofind it. Different people may decide to solve the question in different ways, butall of the correct answers will be the same.If two different methods of solving an equation give you two different answers,then you made a mistake in at least one of them. (Maybe both.)

What are the rules for solving word problems?
The rules for solving word problems are read the problem, decide what you need to do, solve the problem, and check your answer.
How can you decide if a relasionship is linear or not by looking at its equation?
All of the 'X's and 'Y's in the equation must be to the first power only.Otherwise the equation is not linear.
