## How do you calculate simultaneously?

How to solve simultaneous equations

- Use the elimination method to get rid of one of the variables.
- Find the value of one variable.
- Find the value of the remaining variables using substitution.
- Clearly state the final answer.
- Check your answer by substituting both values into either of the original equations.

**What is meant by solving simultaneously?**

Simultaneous equations require algebraic skills to find the values of letters within two or more equations. They are called simultaneous equations because the equations are solved at the same time. Maths.

**What is meant by simultaneous equations?**

a set of two or more equations, each containing two or more variables whose values can simultaneously satisfy both or all the equations in the set, the number of variables being equal to or less than the number of equations in the set.

### How do you do variables on a TI 89?

You can save something as a variable by typing the value, followed by the STO button (to the left of the 1 button on the TI-89 and to the left of the spacebar on the Voyage 200) and then typing a variable name. 12. If you want to clear all the variables you have assigned, press option 1:Clear a-z.

**What are the three types of simultaneous equations?**

If you have two different equations with the same two unknowns in each, you can solve for both unknowns. There are three common methods for solving: addition/subtraction, substitution, and graphing.

**What does it mean to solve two equations simultaneously?**

Simultaneous equations are two equations, each with the same two unknowns and are “simultaneous” because they are solved together.
