You do the following:
1) Solve one of the equations for one of the variables
2) Substitute this variable in the other equation or equations
3) Simplify
This should normally give you one less equation than the original set, with one less variables. For example:
To determine the best variable to solve for in a system of equations by substitution, look for the equation that allows you to isolate a variable easily. Typically, choose the equation where one variable has a coefficient of 1 or -1, or is already expressed in terms of the other variable. This makes substitution straightforward and minimizes complexity in calculations. Once identified, you can solve for that variable and substitute it into the other equation.
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.
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.
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.
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.

You'd need another equation to sub in
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.
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.
You cant solve it unless it is an equation. To be an equation it must have an equals sign.
by elimination,substitution or through the matrix method.
To solve the following equation by substitution, we need to have the equal sign. This will help us group the knowns and the unknowns.
