Math Problem Statement

Find the intersection of the lines: 2x + 3y = 5 and 2x + 3y = 10.

Solution

To find the intersection of the lines:

  1. 2x+3y=52x + 3y = 5
  2. 2x+3y=102x + 3y = 10

We compare these two equations. Notice that the left-hand sides are identical (2x+3y2x + 3y), but the right-hand sides are different (55 and 1010).

Analysis:

If we subtract the first equation from the second, we get: (2x+3y)(2x+3y)=105(2x + 3y) - (2x + 3y) = 10 - 5 0=50 = 5

This is a contradiction. It means that the two lines are parallel and do not intersect.

Conclusion:

The two lines have no point of intersection because they are parallel.

Tip: When two linear equations have the same left-hand side but different right-hand sides, the lines are always parallel!
