Hi there,
Take y from first equation and use it / substitute it into the second equation:
-2x + 8 = x - 1, so 3x = 9, therefore x = 3.
Then y = x - 1 = 3 - 1 => y = 2.
Solution is (3,2).
A quick check: 2 = -2*3 + 8, true, and 3 = 2 - 1, also true.

Answer:
2.97 g
Step-by-step explanation:
First convert mass to moles.
7.72 g Mg × (1 mol Mg / 24.3 g Mg) = 0.318 mol Mg
Use stoichiometry to find moles of nitrogen.
0.318 mol Mg × (1 mol N₂ / 3 mol Mg) = 0.106 mol N₂
Convert moles to mass:
0.106 mol N₂ × (28.0 g N₂ / mol N₂) = 2.97 g N₂
