Yes, for solving simultaneous equations.
True. The elimination method is a technique used in solving systems of equations where you can eliminate one variable by adding or subtracting equations. This simplifies the system, allowing for easier solving of the remaining variable. It is particularly effective when the coefficients of one variable are opposites or can be made to be opposites.
To eliminate a variable in an equation, you can isolate it on one side of the equation by performing inverse operations, such as adding, subtracting, multiplying, or dividing both sides by the same number. If there are multiple variables, you might use substitution or elimination methods, especially in systems of equations. Additionally, you can simplify the equation by combining like terms or factoring. Ultimately, the goal is to isolate the variable or eliminate it through algebraic manipulation.
To solve a system of two equations, you can use one of three methods: substitution, elimination, or graphing. In the substitution method, you solve one equation for one variable and substitute that expression into the other equation. In the elimination method, you manipulate the equations to eliminate one variable by adding or subtracting them. Graphing involves plotting both equations on a graph and identifying their point of intersection, which represents the solution.
To identify an equation for elimination, start with a system of linear equations, typically in the form ( Ax + By = C ). Elimination involves manipulating these equations to eliminate one variable, allowing you to solve for the other. You can do this by multiplying one or both equations by suitable coefficients so that when they are added or subtracted, one variable cancels out. Once one variable is eliminated, you can solve for the remaining variable and then substitute back to find the other.
The addition method is sometimes referred to as the "elimination method." This technique is used in solving systems of linear equations by adding or subtracting the equations to eliminate one variable, making it easier to solve for the other variable.

To solve this system of equations using the elimination method, we need to eliminate one variable by adding or subtracting the two equations. By looking at the equations given (2y-2x-8 = 0 and 3y-18-3x = 0), we can choose to eliminate either the x or y variable. Let's choose to eliminate the x variable: Multiply the first equation by 3 and the second equation by 2 to make the coefficients of x the same: 6y - 6x - 24 = 0 6y - 36 - 6x = 0 Now we can subtract the second equation from the first equation to eliminate x: (6y - 6x - 24) - (6y - 36 - 6x) = 0 Simplify to get -12 = 0, which is a false statement. Therefore, the system of equations is inconsistent and has no solution.
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.
By elimination and substitution
To isolate a variable on one side of an equation, you can perform inverse operations to eliminate other terms. Start by adding or subtracting constants from both sides to move them away from the variable. Then, if the variable is multiplied by a coefficient, divide both sides by that coefficient. Repeat these steps as necessary until the variable stands alone.
When solving a system of linear equations using the elimination method, multiplying the bottom equation by 3 can help align the coefficients of one of the variables, making it easier to eliminate that variable. This step works because it maintains the equality of the equation while allowing for the addition or subtraction of the equations to eliminate the variable effectively. By strategically choosing a multiplier, you can simplify the process of finding the solution to the system.
It does not matter.
