Math Problem Statement

Find the values of x and y in the diagram where the relationships between angles are established due to parallel lines and a transversal. The expressions for angles are given as 2x + 4, 3x - 1, 3y, and 2y + 2.

Solution

To solve the given problem, the corresponding angles in the diagram suggest relationships due to parallel lines and transversal rules. Let us analyze the given equations and their relationships:

From the diagram:

  1. 2x+42x + 4 and 3x13x - 1 are corresponding angles. Therefore: 2x+4=3x12x + 4 = 3x - 1

  2. 3y3y and 2y+22y + 2 are also corresponding angles. Therefore: 3y=2y+23y = 2y + 2

Solving these equations:

Step 1: Solve 2x+4=3x12x + 4 = 3x - 1

2x+4=3x12x + 4 = 3x - 1 Subtract 2x2x from both sides: 4=x14 = x - 1 Add 1 to both sides: x=5x = 5

Step 2: Solve 3y=2y+23y = 2y + 2

3y=2y+23y = 2y + 2 Subtract 2y2y from both sides: y=2y = 2

Final Solution:

x=5,  y=2x = 5, \; y = 2
