The answer to this question is 25. To solve this equation, we need to use the distributive property. The distributive property states that when a number is multiplied by a group of numbers, it is the same as multiplying the number by each number in the group separately and then adding the results together. In this case, we can use the distributive property to multiply 5 by each number in the group (x-1). This gives us 5x - 5. We can then add 5 to both sides of the equation to get 5x = 6. Finally, we can divide both sides of the equation by 5 to get x = 6/5, or 1.25. Therefore, the answer to the equation 5x-1 is 25.
