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 + 7 = -14
-3w = -14 - 7
-3w = -21
w = -21/-3
w = 7
180/3 = 60 and I believe x is 60/2 = 30
Answer:
13 - 17
Step-by-step explanation:
Using the rule
× = a
Each term in the second factor is multiplied by each term in the first factor, that is
2 ( - 9 ) + 1 ( - 9 )
Distribute both parenthesis
= (2 × 11) - 18 + - 9
= 22 - 17 - 9
= 13 - 17
