Answer:

Yes, the equations 3x - 1 = 7 and 3x = 8 have different solutions.

Explanation:

Let's solve each equation separately to find their solutions:

1. Equation 1: 3x - 1 = 7

To solve this equation, we can isolate the variable x by adding 1 to both sides:

3x - 1 + 1 = 7 + 1

3x = 8

Then, we divide both sides of the equation by 3 to solve for x:

(3x)/3 = 8/3

x = 8/3

2. Equation 2: 3x = 8

To solve this equation, we divide both sides of the equation by 3:

(3x)/3 = 8/3

x = 8/3

Comparing the solutions of the two equations, we see that both equations have different solutions. Equation 1 has a solution of x = 8/3, while Equation 2 also has a solution of x = 8/3. Therefore, the two equations have the same solution.

In summary, the equations 3x - 1 = 7 and 3x = 8 have the same solution, which is x = 8/3.
