y-420=600-56 55*x=820-710 300-x=42*2

Here are the equations solved separately (as written):

1. y - 420 = 600 - 56

• 600 - 56 = 544
• y - 420 = 544
• y = 964

2. 55*x = 820 - 710

• 820 - 710 = 110
• 55x = 110
• x = 110 / 55 = 2

3. 300 - x = 42 * 2

• 42 * 2 = 84
• 300 - x = 84
• x = 300 - 84 = 216

Important note:

• The second and third equations both involve x but give different values (x = 2 vs. x = 216). If these are meant to be a single system with the same x, there is no solution because they are inconsistent. If they are independent equations, then the results above apply.

Would you like me to treat them as a system and try to resolve, or check for a possible misprint (e.g., maybe the third equation was 300 - y = 42*2 or something similar)?
