Elimination Method Quiz

What is the first step in using the elimination method to solve a system of equations?

• Multiply the equations by different numbers.

• Align the variables and constants.

• Substitute one equation into the other.

• Graph the equations.

When using the elimination method, what should you do if the coefficients of a variable are already equal but opposite in sign?

• Multiply both equations by zero.

• Add the equations together.

• Divide the equations by the coefficient.

• Subtract the equations from each other.

After eliminating one variable, what is the next step in solving the system of equations?

• Substitute the value back into one of the original equations.

• Graph the remaining equation.

• Check the solution by substituting into both equations.

• Multiply the remaining equation by a constant.

If you have the equation 3x + 4y = 11 and you know x = 1, how do you find y?

• Eliminate x by adding another equation.

• Substitute x = 1 into the equation and solve for y.

• Graph the equation and find the y-intercept.

• Multiply the equation by 2 and solve for y.

What is the final solution to the system of equations if x = 1 and y = 2?

• (1, 2)

• (2, 1)

• (1, -2)

• (0, 0)
