Question

Explain, in complete sentences, how you would use the elimination method to solve the following system of equations and provide the solution to the system.

5x - 3y = 4
3x - 5y = -4

Answer 1

What would you do first?

Answer 2

I Dont Know!

Answer 3

start by solving for x in the 1st equation

Answer 4

how do you get rid of the -3y?

Answer 5

Answer 6

:) You want to eliminate one of the variables by adding the two equations together like this

5x - 3y = 4
3x - 5y = -4
---------------
8x - 8y = 0

This particular addition doesn't give you any useful information, because we haven't eliminated a variable.

How do you think you could alter one or both of these equations it so that adding them together leaves you with either x or y by itself?
