# How do you solve linear equations with multiple variables?

## How do you solve linear equations with multiple variables?

Solve one of the two equations for one of the variables in terms of the other. Substitute the expression for this variable into the second equation, then solve for the remaining variable. Substitute that solution into either of the original equations to find the value of the first variable.

### Can Wolfram Alpha solve simultaneous equations?

In addition to finding solutions to equations, Wolfram|Alpha also plots the equations and their solutions. Solve a set of two or more simultaneous equations.

**How do you solve two linear equations?**

Example 2.

- Step 1: Multiply each equation by a suitable number so that the two equations have the same leading coefficient.
- Step 2: Subtract the second equation from the first.
- Step 3: Solve this new equation for y.
- Step 4: Substitute y = 2 into either Equation 1 or Equation 2 above and solve for x.

**How do you solve a linear equation with three variables?**

Solve Systems of Three Equations in Three Variables

- Interchange the order of any two equations.
- Multiply both sides of an equation by a nonzero constant.
- Add a nonzero multiple of one equation to another equation.

## Which is the best way to solve multivariable linear equations?

Multivariable linear equations are equations that have two or more unknowns (generally represented by ‘x’ and ‘y’). There are multiple ways that you can solve these equations, including elimination and substitution. Method 1 Understanding the Components of Linear Equations Download Article

### How to solve a linear equation with elimination?

Solving a Linear Equation with Elimination Look at your equation. Choose a variable to eliminate. Add or subtract the two equations to remove one of the variables and solve the other variable. Plug in your solution to solve for the remaining variable. Plug your findings into both equations to make sure that they are correct.
