What is the first step in solving a system of equations by elimination?
Rewrite the equations so the variables are all on the same side and line up the like terms.
Get both equations in slope-intercept form.
Get both equations equal to zero.
Put the x terms first.
Answer explanation
We need all of the variables on the same side so that we can eventually add the left side of both equations together and add the right side of both equations together.
If the variables aren't on the same side of the equal-sign, then we can't combine like terms.

MULTIPLE CHOICE QUESTION

To eliminate a variable in the system, should you add the equations or subtract the equations?
Add
Subtract
Neither
Answer explanation
We want to add the equations together in order to eliminate one of the variables. We have opposite terms (3x and -3x) that will "cancel/zero out" (be eliminated) when we add the equations together.
