I will give you a very simple example and you can see how it is done x+y=10 -x+y=30 So if we add these equations together, we eliminate the variable x. We can do this since adding equal thing to other equal things always gives us equal things. So we have 2y=40 or y=20 Now plug that back in either equation. x+20=10 and we have x=-10

How solve systems of equations and inequalities using elimination?
To solve systems of equations using elimination, first align the equations and manipulate them to eliminate one variable. This is often done by multiplying one or both equations by suitable constants so that the coefficients of one variable are opposites. After adding or subtracting the equations, solve for the remaining variable, then substitute back to find the other variable. For inequalities, the same elimination process applies, but focus on determining the range of values that satisfy the inequalities.
When is it best to solve a systems of linear equations using elimination?
Elimination is particularly easy when one of the coefficients is one, or the equation can be divided by a number to reduce a coefficient to one. This makes substitution and elimination more trivial.
Why preferred standard form?
Standard form for equations of two variables is preferred when solving the system using elimination.

Y equals x plus 3 and 3x-y equals 5?
Solve this simultaneous equation using the elimination method after rearraging these equations in the form of: 3x-y = 5 -x+y = 3 Add both equations together: 2x = 8 => x = 4 Substitute the value of x into the original equations to find the value of y: So: x = 4 and y = 7
How do you solve systems of equations by using elimination?

How do you solve for the point of intersection?
Finding the point of intersection using graphs or geometry is the same as finding the algebraic solutions to the corresponding simultaneous equations.
How do you decide whether to use elimination or subsitution to solve a three-variable system?
There is no simple answer. Sometimes, the nature of one of the equations lends itself to the substitution method but at other times, elimination is better. If they are non-linear equations, and there is an easy substitution then that is the best approach. With linear equations, using the inverse matrix is the fastest method.
How do you know whether you should add or subtract when using the elimination method?
When using the elimination method to solve a system of equations, you should add the equations if doing so will eliminate one variable. This typically occurs when the coefficients of that variable are opposites (e.g., +2 and -2). Conversely, you should subtract the equations if their coefficients are the same, which will also help to eliminate that variable. Ultimately, the goal is to manipulate the equations to create a situation where one variable cancels out.
