Simultaneous Equations Homework Statement: Solving with Two Variables

In summary, simultaneous equations are a system of equations that must be solved at the same time and contain two or more variables. Their purpose is to find the values of the variables that make all equations in the system true, which allows for the determination of the intersection point of lines or curves on a graph. These equations can be solved using methods such as substitution, elimination, or graphing, with substitution being the most common. Simultaneous equations can have any number of variables, but the number of equations must match in order for there to be a unique solution. They are commonly used in physics, engineering, and economics, as well as other fields such as chemistry, biology, and computer science.

Homework Statement



Eq 1: (4.5 - V1)/470 = V1/680 + (V1-V2)/330

Eq 2: (V1-V2)/330 = V2/100 + (V2+7)/1000

The equations use two variables to the first power. Clear the fractions using lowest common denominators , then simplify the equations. You only have two equations and two unknowns. Use either elimination or substitution.
 

Related to Simultaneous Equations Homework Statement: Solving with Two Variables

1. What are simultaneous equations?

Simultaneous equations are a system of equations that contain two or more variables. They are called "simultaneous" because they must be solved at the same time.

2. What is the purpose of solving simultaneous equations?

The purpose of solving simultaneous equations is to find the values of the variables that make all of the equations in the system true. This allows us to find the intersection point of two or more lines or curves on a graph.

3. How do you solve simultaneous equations?

There are several methods for solving simultaneous equations, including substitution, elimination, and graphing. The most common method is substitution, where one equation is solved for one variable and then that value is substituted into the other equation.

4. Can simultaneous equations have more than two variables?

Yes, simultaneous equations can have any number of variables. However, the number of equations in the system must be equal to the number of variables in order for there to be a unique solution. Otherwise, there may be multiple solutions or no solutions at all.

5. In what fields of science are simultaneous equations commonly used?

Simultaneous equations are commonly used in physics, engineering, and economics to model and solve real-world problems. They can also be found in other fields such as chemistry, biology, and computer science.
