## How do you simplify a system of equations?

Here’s how it goes:

1. Step 1: Solve one of the equations for one of the variables. Let’s solve the first equation for y:
2. Step 2: Substitute that equation into the other equation, and solve for x.
3. Step 3: Substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.

### What makes a system of equations dependent?

If a consistent system has exactly one solution, it is independent . If a consistent system has an infinite number of solutions, it is dependent . When you graph the equations, both equations represent the same line.

How do you write system of equations?

What is the best method for solving a system of equations?

The three methods most commonly used to solve systems of equation are substitution, elimination and augmented matrices. Substitution and elimination are simple methods that can effectively solve most systems of two equations in a few straightforward steps.

## How to solve a system of equations algebraically?

Methods for Solving Systems of Equations Algebraically. Type 2: One variable can be easily isolated. The systems are solved by solving for one variable in one of the equations, then substituting that equation into the second equation. Solve for a in the second equation, then substitute the second equation into the first.

### How is a system of equations solved type 2?

The system is solved by substituting the equation with the isolated term into the other equation: Type 2: One variable can be easily isolated. The systems are solved by solving for one variable in one of the equations, then substituting that equation into the second equation.
