The first step of Elimination in solving a system is to find opposites of one of the variable terms. Explain in your own words, why you need to find opposite terms to solve a system of equations using the Elimination method.
You need to find opposite terms when using the elimination method to solve a system of equations so that way you can find out the y or the x after you have crossed out the fraternal twins. You have to get rid of either the y or x in order to work it out and find the y or x value.
Well you need to find the opposite term so that you can plug it back in to the original question to solve for the variable you want with no other variables. Hope This Helps!
