Hi,

Solving using the Substitution Method

2x+y=6 OR y = -2x+6

5x+4y=0 

5x + 4(-2x+6) = 0

       -3x = -24

         x = 8 and y = -10

Ordered pair (8,-10) is the solution for this system of EQs



CHECKING our Answer***Using Elimination Method

2x+y=6 

5x+4y=0 



-8x-4y=-24   |Multiplying 1st EQ thru by -4, so as to eliminate y

5x +4y = 0

 -3x = -24

   x = 8  and y = -10 (y = -2x+6)
