Answer: Hi

Explanation:

The equation for the line y = p - 3x can be rearranged as y + 3x = p.

Substituting this into the system of equations, we get:

4x - (y + 3x) = 6

4x - y - 3x = 6

x = 6

2x - 5y = 12

2(6) - 5y = 12

12 - 5y = 12

-5y = 0

y = 0

So the point of intersection is (6, 0).

Substituting these values into y = p - 3x, we get:

0 = p - 3(6)

0 = p - 18

p = 18

Therefore, the value of p that makes the line y = p - 3x pass through the point of intersection of the lines 4x - y = 6 and 2x - 5y = 12 is 18.
