Answer:
Step-by-step explanation:
Using elimination means you either add the two equations together or subtract them. You can first multiply the second equation by 2, so you get 4x - 6y = 24. Then you add the two equations together to get 9x = 42. Then you solve for x and then you can solve for y.

Answer:
Step-by-step explanation:
The photo for the question is not given. I have searched and attached it.
From the attached photo, the inequality is
-2x/3 + 9 > 7
By simplifying, subtract 9 from both sides of the inequality. It becomes
-2x/3 + 9 - 9 > 7 - 9
- 2x/3 > - 2
Multiplying both sides of the inequality by - 3/2, the inequality symbol would change due to the negative sign. It becomes
- 2x/3 × 3/2 < - 2 × - 3/2
x < 3
Therefore,
Yuto is correct because he isolated the variable correctly and reversed the inequality symbol.
