Answer: No. When 1 is substituted for the variable, the result is a false statement

Explanation:

3x - 6(5x + 5) = 9x + 6

3x - 30x - 30 = 9x + 6

-27x -30 = 9x +6

-27x - 9x = 30 +6

-36x = 36

x = -1.

Substitute with x = -1 :

-3 - 6(-5 + 5) = -9 +6

-3 -30 + 30 = -3

-3 = -3

Therefore, the correct option is:

No. When 1 is substituted for the variable, the result is a false statement
