−9=3−3(x+3)

Answer 1

First, we can simplify the equation by distributing the -3:

-9 = 3 - 3x - 9

Next, we can combine like terms:

-9 = -6 - 3x

Then, we can isolate the variable by adding 6 to both sides:

-3 = -3x

Finally, we can solve for x by dividing both sides by -3:

x = 1

Therefore, the solution to the equation -9 = 3 - 3(x+3) is x = 1.
