Question

−3(x + 3) = −3(x + 1) − 5

Answer 1

solve for x?

Answer 2

-3(x+3) means -3 times each term inside the parens

in other words -3(x+3) can be re-written as -3*x + -3*3
so your problem can be written as
-3*x + -3*3 = -3(x+1) - 5

can you do the same thing for the right side ?

Answer 3

it would end up being -3x -9 = -3x - 8

which doesn't make sense unless x is infinity

Answer 4

yes, it looks like there is no solution for this "equation"
