Answer:
To find equations that have the same solution as 2x-5=15, we need to solve the given equation first:
2x - 5 = 15
Adding 5 to both sides:
2x = 20
Dividing both sides by 2:
x = 10
Now, we can check the options to find equations with the same solution:
1. 3x + 2 = 32
Substituting x = 10:
3(10) + 2 = 30 + 2 = 32 (same solution)
2. x^2 - 100 = 0
Substituting x = 10:
10^2 - 100 = 100 - 100 = 0 (same solution)
3. 4x + 8 = 42
Substituting x = 10:
4(10) + 8 = 40 + 8 = 48 (not the same solution)
Therefore, equations 1 and 2 have the same solution as 2x-5=15.
