Answer:
Option 3
Step-by-step explanation:
We need to find a pair which shows equivalent expressions.
First equation is
![2x+10=-2(x-5)](https://tex.z-dn.net/?f=2x%2B10%3D-2%28x-5%29)
![LHS=2x+10](https://tex.z-dn.net/?f=LHS%3D2x%2B10)
![RHS=-2(x-5)=-2(x)-2(-5)=-2x+10](https://tex.z-dn.net/?f=RHS%3D-2%28x-5%29%3D-2%28x%29-2%28-5%29%3D-2x%2B10)
![LHS\neq RHS](https://tex.z-dn.net/?f=LHS%5Cneq%20RHS)
Option 1 is incorrect.
Second equation is
![-2(x+5)=2x-10](https://tex.z-dn.net/?f=-2%28x%2B5%29%3D2x-10)
![LHS=-2(x+5)=-2(x)-2(5)=-2x-10](https://tex.z-dn.net/?f=LHS%3D-2%28x%2B5%29%3D-2%28x%29-2%285%29%3D-2x-10)
![RHS=2x-10](https://tex.z-dn.net/?f=RHS%3D2x-10)
![LHS\neq RHS](https://tex.z-dn.net/?f=LHS%5Cneq%20RHS)
Option 2 is incorrect.
Third equation is
![-2x-10=-2(x+5)](https://tex.z-dn.net/?f=-2x-10%3D-2%28x%2B5%29)
![LHS=-2x-10](https://tex.z-dn.net/?f=LHS%3D-2x-10)
![RHS=-2(x+5)=-2(x)-2(5)=-2x-10](https://tex.z-dn.net/?f=RHS%3D-2%28x%2B5%29%3D-2%28x%29-2%285%29%3D-2x-10)
![LHS=RHS](https://tex.z-dn.net/?f=LHS%3DRHS)
Option 3 is correct.
Fourth equation is
![-2(x–5)=-2X-10](https://tex.z-dn.net/?f=-2%28x%E2%80%935%29%3D-2X-10%E2%80%8B)
![LHS=-2(x–5)=-2(x)-2(-5)=-2x+10](https://tex.z-dn.net/?f=LHS%3D-2%28x%E2%80%935%29%3D-2%28x%29-2%28-5%29%3D-2x%2B10)
![RHS=-2x-10](https://tex.z-dn.net/?f=RHS%3D-2x-10)
![LHS\neq RHS](https://tex.z-dn.net/?f=LHS%5Cneq%20RHS)
Option 4 is incorrect.
Therefore, the correct option is 3.
