Question 1205725
.
So, my problem is this I solved it once and I got it wrong can you guys help me out?
8x-6y=-2
8x+5y=-13
I am supposed to use the elimination method and get an ordered pair and I am still confused.

Nice problem for the Elimination method.

Simply subtract first equation from the second equation.

The terms '8x' and '8x' will cancel (will kill / will annihilate) each other,
and you will get

    5y - (-6y) = -13 - (-2)

    5y + 6y = -13 + 2

      11y   =    -11

        y   =  {{{-11/11}}} = -1


Thus you just found out one unknown: y = -1.


Now substitute this value  y= -1  into first equation

    8x + 5*(-1) = -13

    8x - 5 = -13

    8x = -13 + 5 

    8x = -8

     x = {{{(-8)/8}}} = -1.


<U>ANSWER</U>.  x= -1,  y= -1.

Solved.
