Math Problem Statement

Solve the equation 6 / (5x - 3) = 5 / (x + 1) and simplify the answer fully.

Solution

The equation in the image is:

65x3=5x+1\frac{6}{5x - 3} = \frac{5}{x + 1}

To solve for xx, follow these steps:

  1. Cross-multiply the terms to eliminate the fractions:

6(x+1)=5(5x3)6(x + 1) = 5(5x - 3)

  1. Expand both sides:

6x+6=25x156x + 6 = 25x - 15

  1. Move all terms involving xx to one side and constants to the other side:

6x25x=1566x - 25x = -15 - 6

19x=21-19x = -21

  1. Solve for xx by dividing both sides by 19-19:

x=2119=2119x = \frac{-21}{-19} = \frac{21}{19}

Thus, the solution is:

x=2119x = \frac{21}{19}
