X=0 and y=0
You can solve the system of equations with three variables using the substitute method, or using matrix operations.
solve system equation using addition method 3x-y=9 2x+y=6
To solve a system of equations, you need equations (number phrases with equal signs).
Awnser = Start paying attention in class.
The answer depends on whether they are linear, non-linear, differential or other types of equations.
y=7x-8 42x-48=6y

True
Solve the problem using the + sign for the variable. Then solve the problem using the - sign for the variable. Report your answer as the answer that you got using + or the answer that you got using -.
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.
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.
