x = 4

#### Work Step by Step

5x - 1 = x + 15 First, you need to get the variable (x) on one side of the equation, so subtract x from both sides of the equation. This will remove the x from the right side of the equation. 5x - 1 - x = x + 15 - x Simplify to get this: 4x - 1 = 15 Add 1 to each side. 4x - 1 + 1 = 15 + 1 Simplify to get: 4x = 16 Divide each side by 4. $\frac{4x}{4}$ = $\frac{16}{4}$ Simplify to x = 16 $\div$ 4 x = 4
