Elimination Method in Systems of Equations

What is the first step in solving a system of equations using elimination?

• Add the equations together.

• Multiply one or both equations to make coefficients the same or opposite.

• Subtract the equations.

• Check the solution.

When should you add the equations in the elimination method?

• When the equations are already solved.

• When the coefficients are opposites.

• When the variables are different.

• When the coefficients are the same.

What is a zero pair in the context of solving equations?

• A pair of numbers that add up to zero.

• A pair of equations that have no solution.

• A pair of variables that are the same.

• A pair of coefficients that are both positive.

Why might you need to multiply an equation by a factor in the elimination method?

• To change the variables.

• To make the coefficients the same or opposite.

• To solve the equations faster.

• To make the equations longer.

What should you do after finding the values of the variables in a system of equations?

• Add the solution to the original equations.

• Multiply the solution by a factor.

• Check if the solution satisfies both original equations.

• Ignore the solution.
