Solve. \( 15 x+13-5 x=5 x+8 \)

To solve the equation \( 15x + 13 - 5x = 5x + 8 \), start by simplifying the left side. Combine like terms: \( (15x - 5x) + 13 = 5x + 8 \) This simplifies to: \( 10x + 13 = 5x + 8 \) Next, isolate the \(x\) terms by subtracting \(5x\) from both sides: \( 10x - 5x + 13 = 8 \) This simplifies to: \( 5x + 13 = 8 \) Now, subtract \(13\) from both sides: \( 5x = 8 - 13 \) Which gives: \( 5x = -5 \) Finally, divide by \(5\): \( x = -1 \) So, the solution is \( x = -1 \).
