To answer this, I'll use an example:
Say you're equations are both in slope-intercept form:
y = 3x + 5
y = x + 7
You substitute one equation into another (since y = y, you can set it up in the same equation).
x + 7 = 3x + 5
Subtract variables.
7 = 2x +5
Subtract numbers.
2 = 2x
Divide.
1 = x
You could also have a problem with one or two standard form equations. First, make sure you have at least one slope-intercept equation. Here's an example:
3x - 2y = 20
y = x + 15
Substitute the slope-intercept equation into y (because y = y).
3x - 2(x + 15) = 20
Distribute.
3x- 2x - 30 = 20
Like terms!
x - 30 = 20
Add 30 to both sides.
x = 50
For both equations, you can substitute your solution into one of the equations to find the other variable.

What is the use of gaussian elimination in education world situations?
Gaussian elimination is used to solve systems of linear equations.
What are the applications of linear transformations?
Linear transformations can be very important in graphics. Also, linear transformations come up whenever you need to solve systems of linear equations, which arise quite often. Finally, they can be useful in further areas of mathematics such as topology.
Solve linear equations with complex coefficients on both sides?
You would solve them in exactly the same way as you would solve linear equations with real coefficients. Whether you use substitution or elimination for pairs of equations, or matrix algebra for systems of equations depends on your requirements. But the methods remain the same.
How do you solve linear equations?
I DON'T KNOW...... TEACH ME!!?!?!?!?!?!
How do you solve linear problem?
If you are trying to solve a linear equation and facing difficulty in doing so then try to understand that the variable which u have taken is depending on what factor..and equate it with the constant..by doing this you will be able to solve the equation.
What does it mean by solving linear systems?
Solving linear systems means to solve linear equations and inequalities. Then to graph it and describing it by statical statements.
Is linear algebra and linear equations the same?
Linear Algebra is a branch of mathematics that enables you to solve many linear equations at the same time. For example, if you had 15 lines (linear equations) and wanted to know if there was a point where they all intersected, you would use Linear Algebra to solve that question. Linear Algebra uses matrices to solve these large systems of equations.
What has the author Laenas Gifford Weld written?
Laenas Gifford Weld has written: 'A short course in the theory of determinants' -- subject(s): Determinants, Substitutions, Linear, Linear Substitutions
What is the first step in solving a system of nonlinear equations by substitutions?
In general, a system of non-linear equations cannot be solved by substitutions.
How can you solve a system of equations?
The answer depends on whether they are linear, non-linear, differential or other types of equations.

How do you solve a linear inequalities?
to solve a linear in equality you have to write it out on a graph if the line or shape is made ou of strate lines its linear
What are 2 symbolic techniques used to solve linear equations and which is better?
There are more than two methods, and of these, matrix inversion is probably the easiest for solving systems of linear equations in several unknowns.
When was Non-Linear Systems created?
Non-Linear Systems was created in 1952.
