It often doesn't matter which one you solve for first. But if you can easily solve one of the equations for one of the variables, that's the one you should solve for.

How do you solve systems by using the substitution method?
You solve one of the equation for one of the variables. For example, if the variables involved are "x" and "y", you might solve for "y". It doesn't really matter what variable you solve for first, so you can solve for whatever variable is easiest to solve. Then - assuming you got, for example, "y = 3x -1", in this example you would replace every "y" by "3x - 1" in the other equation or equations.
What comes first independent or dependent variable?
Independent variable
What is the first step in solving the following system of equations by substitution?
The first step is to show the equations which have not been shown.
Why is the output value called the dependent variable?
because it can change according to the independent variable. this dependent variable depends on the independent variable for its output. the independent variable is not affected by the dependent variable because the independent variable if found out first.
What comes first in an equation a variable or a number?
A variable comes after the number 2n+5n=7n
When using the substitution method to solve a nonlinear system of equations you should first see if you can one variable in one of the equations in the system?
isolate
Which is most likely the first step in solving a system of nonlinear equations by substitution APEX?
Isolating a variable in one of the equations.
When using the substitution to solve nonlinear system of equations you should first see if you can one variable if you can one variable in one of the equation in the system?
The general idea is to solve one of the equations for one variable - in terms of the other variable or variables. Then you can substitute the entire expression into another equation or other equations; as a result, if it works you should end up having one less equation, with one less variable.

What is usually the first step in solving a system of nonlinear equations by substitution?
The first step is usually to solve one of the equations for one of the variables.Once you have done this, you can replace the right side of this equation for the variable, in one of the other equations.
How do you calculate fixed and variable cost of various products?
First of all total cost of product is identified and after that using high and low method variable and fixed costs are segregated
in scientific method which should come first?
The first step in the Scientific Method is to make objective observations
What is a blood substitution?
A blood substitution is a rule in rugby where a temporary substitution is made for a visibly-bleeding player who must leave the field of play for first-aid treatment.
Why do you write void to the first of main?
Because main is the first method being executed, the Java Virtual Machine cannot expect any return values from this method. Since void is the term used to refer to a variable that does not return any value, we use the key word void for the method signature of the main method
What should be stated in the first step of scientific method?
