I would say that y = x - 8
then I would say
-3x - 2(x-8) = 16
I would solve that for x
and use that x to go back and find y
how would you solve this with substitution?
-3x – 2y = 16
-x + y = -8

from the 2nd, y = x-8
now sub that into the 1st:
-3x - 2(x-8) = 16
-3x - 2x + 16 = 16
-5x = 0
x = 0
y = 0 - 8 = -8
now sub that into the 1st:
-3x - 2(x-8) = 16
-3x - 2x + 16 = 16
-5x = 0
x = 0
y = 0 - 8 = -8
