Math Problem Statement

(x-1) /(x+5)=5/3

Solution

To solve the equation:

x1x+5=53\frac{x-1}{x+5} = \frac{5}{3}

Step 1: Cross-multiply to eliminate the fractions.

3(x1)=5(x+5)3(x-1) = 5(x+5)

Step 2: Expand both sides.

3x3=5x+253x - 3 = 5x + 25

Step 3: Move all terms involving xx to one side and constants to the other side.

3x5x=25+33x - 5x = 25 + 3 2x=28-2x = 28

Step 4: Solve for xx.

x=282=14x = \frac{28}{-2} = -14

So, the solution is: x=14x = -14
