That is called 'solving'.
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.
substitution
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.
Yes, algebraic expressions can be solved, depending on the type of expression and the variable(s) involved. If the expression has a single variable, it can typically be solved for that variable using algebraic techniques such as simplifying, factoring, or isolating the variable. However, if the expression has multiple variables or complex operations, solving it may require more advanced algebraic techniques or numerical methods.

The second step when solving a system of nonlinear equations by substitution is to solve one of the equations for one variable in terms of the other variable(s). Once you have expressed one variable as a function of the other, you can substitute that expression into the other equation to create a single equation in one variable. This allows for easier solving of the system.
An expression using a variable could be ( 3x + 5 ), where ( x ) represents a number. In this expression, ( 3x ) indicates three times the value of ( x ), and ( 5 ) is a constant added to it. This type of expression can be used in various mathematical contexts, such as solving equations or modeling real-world situations.
When you replace a variable with a value that results in a true sentence, it is referred to as "satisfying" the variable or "making the statement true." This process is often seen in mathematics and logic, where substituting specific values into an equation or expression yields a true statement. For example, if you have the equation (x + 2 = 5) and substitute (x = 3), the statement becomes true. This concept is fundamental in solving equations and understanding logical expressions.
What given?
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.
The first step in solving a multistep equation with an expression in parentheses is to apply the distributive property, if necessary, to eliminate the parentheses. This involves multiplying the term outside the parentheses by each term inside. After simplifying, you can then combine like terms and isolate the variable to solve the equation.
You may want to be a little more specific about what your question is asking....... you can solve a variable in an equation or expression. For example: 1+2=y just remember, you arnt necessarily "solving" a variable, but I guess you could say that considering a variable can change continuously. Be sure to consider that if you do "solve" a variable you end up with a constant ( a never-changing number) therefore, it is no longer a variable, but just an answer. Hope that helped! :-)
