Answer:
w= -3
Step-by-step explanation:
To solve for w, we need to get w by itself. To solve, do the opposite of what is being done, and whatever is done to one side, needs to be done to the other.
30 = –6w + 12
First, subtract 12 from both sides, since it is being added
30-12= -6w +12-12
18= -6w
Divide both sides by -6, since it is being multiplied
18/-6= -6w/-6
The -6s on the right cancel, and we are left with
-3= w
