Step-by-step 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
