You need as many equations as you have variables.
You can solve the system of equations with three variables using the substitute method, or using matrix operations.
A calculator can be used to proportions to answer a equation. This is easier to solve when having variables on both sides.
algebra involves equations with numbers a variables and your goal is to solve for the variable
Solve for variables using equations graphs and tables. There is also a lot of substituting

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.
By substitution or elimination of one of the variables which usually involves simultaneous or straight line equations.
Because this equation has four variables, it would require four unique equations involving only these four variables to solve.
Solve simultaneous equations of up to 29 variables.

You need two independent linear equations to solve for two unknown variables.
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.
you cannot solve this without more information. When 3 variables are involved, you need 2 equations to solve for the answers for both variables.
