Yes, a system of linear equations can be solved by substitution. This method involves solving one of the equations for one variable and then substituting that expression into the other equation. This process reduces the system to a single equation with one variable, which can then be solved. Once the value of one variable is found, it can be substituted back to find the other variable.
What else can I help you with?
How can you solve a linear equation?
by elimination,substitution or through the matrix method.
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.
When is it better to use substitution to solve a system of equations rather than graphing?
Substitution is often preferable when one equation in a system is easily solvable for one variable, making it straightforward to substitute into the other equation. This method is particularly useful when dealing with linear equations that have coefficients or constants that simplify calculations. Additionally, substitution can be more efficient for systems involving non-linear equations or when precise solutions are needed, as graphing may lead to inaccuracies in identifying intersection points.
How do use substitution when solving system of equations?
You use substitution when you can solve for one variable in terms of the others. By substituting, you remove one variable from the equation, which can then be solved. Once you solve for one variable, you can use substitution to find the other.
Which equation shows the correct substitution for the following system?
To provide the correct substitution for a given system of equations, I would need the specific equations from that system. Typically, you would solve one of the equations for one variable and then substitute that expression into the other equation. If you can provide the equations, I can help you determine the correct substitution.

What is the disadvantage of using the substitution method in solving linear equations rather than the graph method?
There are no disadvantages. There are three main ways to solve linear equations which are: substitution, graphing, and elimination. The method that is most appropriate can be found by looking at the equation.

How do you use substitution to solve a problem?
To use substitution to solve a problem, first, identify one equation in a system of equations and solve it for one variable in terms of the other(s). Next, substitute this expression into the other equation(s) to eliminate the variable. This results in a single equation with one variable, which you can then solve. Finally, substitute back to find the values of the other variables.
How do you solve system of equations by using the substitution method?
To solve a system of equations using the substitution method, first, solve one of the equations for one variable in terms of the other. Then, substitute this expression into the other equation to eliminate that variable. This will result in a single equation with one variable, which can be solved for its value. Finally, substitute this value back into the original equation to find the value of the other variable.
How would use solve the system of equation x plus 3y equals 23 by using substitution?
You'd need another equation to sub in
What is usually the first step in solving a system of equation by substitution?
The first step is to solve one of the equations for one of the variables. This is then substituted into the other equation or equations.
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.
