Question

Solve using the elimination method. Show your work. If the system has no solution or an infinite number of solutions, state this.
9x – 2y = 88
-9x + 2y = -88

Answer 1

if you multiply any one of the equations by (-1) you will get the second

Answer 2

so you have an infinite number of solutions

Answer 3

multiply (-9x+2y=-88)by -1 and you get 9x-2y=88. So, there are infinite many solutions- it is any pair of (x;y) that statisfies equation 9x-2y=88

Answer 4

So there is an infinite number of solutions and not just one specific answer to post?
