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
How can you use substitution method to solve a system of equations that does not have a variable with a coefficient of 1 or - 1?
To use the substitution method on a system of equations without a variable with a coefficient of 1 or -1, you first isolate one variable in one of the equations. For instance, if you have the equations (2x + 3y = 6) and (4x - y = 5), you can solve the first equation for (y), resulting in (y = (6 - 2x)/3). Next, substitute this expression for (y) into the second equation, allowing you to solve for (x). Finally, substitute the value of (x) back into one of the original equations to find the corresponding value of (y).
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.
Which situation may cause someone to use substitution in order to solve a system of equations?
Substitution is often used when one of the equations in a system is already solved for one variable, or can be easily manipulated to do so. For example, if you have the equations (y = 2x + 3) and (3x + 2y = 12), substituting the expression for (y) from the first equation into the second allows for straightforward solving. This method is particularly useful when dealing with linear equations, as it simplifies the process of finding the variable values.
What is most likely to be the first step in solving a system of nonlinear equations by substitution?
The first step in solving a system of nonlinear equations by substitution is to isolate one variable in one of the equations. This involves rearranging the equation to express one variable in terms of the other(s). Once you have this expression, you can substitute it into the other equation(s) in the system, allowing you to solve for the remaining variables.
How do you solve system of eqaution by subsitution?
To solve a system of equations by substitution, first solve one of the equations for one variable in terms of the other. Then, substitute this expression into the other equation. This will give you an equation with only one variable, which you can solve. Finally, substitute back to find the value of the other 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
How do you evaluate expressions by substitution?
To evaluate expressions by substitution, first identify the variable(s) in the expression and determine their corresponding values. Replace each variable in the expression with its given value. Finally, perform the necessary arithmetic operations to simplify the expression and obtain the final result. For example, if the expression is (2x + 3) and (x = 4), substitute to get (2(4) + 3), which simplifies to (8 + 3 = 11).
