Sagot :
Answer:
Option 3
Step-by-step explanation:
The first and second option can be eliminated immediately because the first equation simplified is:
2x + 10 = -2(x - 5)
2x + 10 = -2x + 10
The second equation expanded is:
-2(x + 5) = 2x - 10
-2x - 10 = 2x - 10
The third equation expanded is:
-2x - 10 = -2(x + 5)
-2x - 10 = -2x - 10
Meaning this equation is correct.
The fourth equation expanded is:
-2(x - 5) = -2x - 10
-2x + 10 = -2x - 10
Option 3 is the only correct option.
Hope this helps!
