How do you solve #-19(-3 + x) = -304#?
You can do the opposite of the order of operations.
Start with the multiplication, instead of multiplying the -19, divided it from -304, giving you 16.
Now you have -3+x, this can be switched around to x-3.
Instead of subtracting the 3, add it to the other side,
giving you 19.
This results in x=19
