7,4 2 *2 0 5

I’m not sure what the lines represent. Could you share the exact problem statement or what these numbers mean (e.g., is this an augmented matrix for a system of equations, or something else)?

If we assume it’s an augmented matrix for a 2-variable system:

Line 1: 7 4 | 2 Line 2: 2 0 | 5

Then the system is:

• 7x + 4y = 2
• 2x = 5 => x = 2.5 Plug into first: 7(2.5) + 4y = 2 ⇒ 17.5 + 4y = 2 ⇒ 4y = -15.5 ⇒ y = -3.875

So the solution would be x = 2.5, y = -3.875.

If the second row is meant to be -2 0 | 5 (i.e., the star denotes a minus), then:

• 7x + 4y = 2
• 2x = -5 => x = -2.5 Then 7(-2.5) + 4y = 2 ⇒ -17.5 + 4y = 2 ⇒ 4y = 19.5 ⇒ y = 4.875

Please confirm which is correct (or provide the full problem), and I’ll solve it cleanly.
