1. Problem Description

The image presents several math problems: finding the intersection point of pairs of lines and finding the equation of a line that passes through a given point and is parallel to a given line. I will solve problem number 1, finding the intersection point of the lines x2y4=0x - 2y - 4 = 0 and 2x+3y1=02x + 3y - 1 = 0.

2. Solution Steps

We need to solve the system of equations:
x2y4=0x - 2y - 4 = 0 (1)
2x+3y1=02x + 3y - 1 = 0 (2)
From equation (1), we can express xx in terms of yy:
x=2y+4x = 2y + 4 (3)
Substitute (3) into (2):
2(2y+4)+3y1=02(2y + 4) + 3y - 1 = 0
4y+8+3y1=04y + 8 + 3y - 1 = 0
7y+7=07y + 7 = 0
7y=77y = -7
y=1y = -1
Now, substitute y=1y = -1 back into (3):
x=2(1)+4x = 2(-1) + 4
x=2+4x = -2 + 4
x=2x = 2
Therefore, the intersection point is (2,1)(2, -1).

3. Final Answer

The intersection point of the lines x2y4=0x - 2y - 4 = 0 and 2x+3y1=02x + 3y - 1 = 0 is (2,1)(2, -1).
