Answer 2

To solve the equation 5x - 7 = 3, we can isolate the variable x on one side of the equation. Here's the step-by-step solution:

1. Start with the equation: 5x - 7 = 3.
2. Add 7 to both sides of the equation to get rid of the -7: 5x - 7 + 7 = 3 + 7. This simplifies to: 5x = 10.
3. Divide both sides of the equation by 5 to isolate x: (5x)/5 = 10/5. This simplifies to: x = 2.

Therefore, the solution to the equation 5x - 7 = 3 is x = 2.
