Answer:
Step-by-step explanation:
-3w + 7 = -14
subtract 7 from both sides
-3w + 7 - 7 = - 14 -7
-3w = -21
divide both sides by (-3)
-3w/-3 = -21/-3
w = 7
In short:
-3w = -14 - 7
w = -21/-3
The answer is 7.
Using the rules of PEMDAS, you have to figure out what number multiplied by -3, then plus 7, gives you 14. So, I just substituted 1 - 7 into W and I got -3(7) + 7 = -14.
Hope this helped ^^
