y=2x+9 and y=x+6
You plug in what the variable is equal to for that variable then you will be able to finish the problem
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.
You cant solve it unless it is an equation. To be an equation it must have an equals sign.
3(5x-2y)=18 5/2x-y=-1
When you construct and use a table to solve a problem, you are using a numerical approach.
You solve this by theoretically diverting the hypotenuse of the x divided by the overall beneficial procedure of y

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 -.
You can solve lineaar quadratic systems by either the elimination or the substitution methods. You can also solve them using the comparison method. Which method works best depends on which method the person solving them is comfortable with.

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.
The answer depends on that the problem is!
3(5x-2y)=18 5/2x-y=-1
True

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.
