Using the elimination method, which variable should be eliminated first?

• x is ready to be eliminated without any changes to the equations

• y is ready to be eliminated without any changes to the equations

• x, but you have to multiply one of the equations by -1 to change the signs

• y, but you have to multiply one of the equations by -1 to change the signs

The first step is solving a linear system using the elimination method is ...

• make sure the equations are lined up

• add or subtract the equations to eliminate the variable with matching coefficients

• solve the new equation for the remaining variable

• substitute your solved variable into either original equation and solve for the other variable.
