I will post the problem right after this is posted.

Answer 1

Ok so substitution is done by isolating 1 variable in 1 equation, so pick 1 equation and 1 variable then solving for that variable

Answer 2

@phi

Answer 3

i dont think thats right

Answer 4

y = -34 - 2x

3x + 5y = -9

3x - 170 - 10x = - 9

-7x = 161

x = 161/-7 = -23

y = -34 + 46 = 12
