Step-by-Step Solution

Step 1: Eliminate the variable from one side
Start by subtracting 50x from both sides to gather all x-terms on the left:

75x - 50x = 50x + 2000 - 50x
25x = 2000

Step 2: Solve for x
Now divide both sides by 25:

Final Thoughts

x = 2000 ÷ 25
x = 80


Final Answer

The solution to the equation 75x = 50x + 2000 is:

x = 80
