An equation is a statement. If it includes a variable, then it's only true for certain values
of the variable and false for all others, and to "solve" it means to find those values.
An equation without variables is also a statement. Either the statement is true
or else it isn't. If the statement isn't true, then it's not an equation. Either way,
it was nice of someone to hand it to you, but there's nothing that needs to be
done with it. It asks no question, poses no problem, and seeks no solution.
What else can I help you with?
How doI solve system of equations by substitution?
Assuming the simplest case of two equations in two variable: solve one of the equations for one of the variables. Substitute the value found for the variable in all places in which the variable appears in the second equation. Solve the resulting equation. This will give you the value of one of the variables. Finally, replace this value in one of the original equations, and solve, to find the other variable.
What does it mean to solve a system of linear equations?
Find values for each of the unknown variables (or at least as many as is possible for the system) that satisfy all the equations.
How do you solve radical equations with variables on both sides?
First, get the radical by itself. Then, square both sides of the equation. Then just solve the rest.
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.
What does it mean to solve a system?
Finding a set of value for the set of variables so that, when these values are substituted for the corresponding variables, all the equations in the system are true statements.
How do you solve multivariable equations?
You need as many equations as you have variables.
How do you solve x plus 2y plus 6 equals 0?
you cannot solve this without more information. When 3 variables are involved, you need 2 equations to solve for the answers for both variables.
How do you solve 3 dimensional equations?
You can solve the system of equations with three variables using the substitute method, or using matrix operations.
How can you use proportions to solve equations with variables on both sides?
A calculator can be used to proportions to answer a equation. This is easier to solve when having variables on both sides.
How doI solve system of equations by substitution?
Assuming the simplest case of two equations in two variable: solve one of the equations for one of the variables. Substitute the value found for the variable in all places in which the variable appears in the second equation. Solve the resulting equation. This will give you the value of one of the variables. Finally, replace this value in one of the original equations, and solve, to find the other variable.
How do you solve an equation with two variables?
By substitution or elimination of one of the variables which usually involves simultaneous or straight line equations.
How do you solve x equals t-yz?
Because this equation has four variables, it would require four unique equations involving only these four variables to solve.
What do you mean by algebra?
algebra involves equations with numbers a variables and your goal is to solve for the variable
What does John Atanasoff electronic computer do?
Solve simultaneous equations of up to 29 variables.
What do you do in Algebra?
Solve for variables using equations graphs and tables. There is also a lot of substituting
How do you solve x-y equals 13?
You need two independent linear equations to solve for two unknown variables.
Translate this word problem as a system of equations and then solve using substitution?
A system of equations is two or more equations that share at least one variable. Once you have determined your equations, solve for one of the variables and substitute in that solution to the other equation.
