Question

how would you solve this with substitution?

-3x – 2y = 16
-x + y = -8

Answer 1

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

Answer 2

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
