Answer:
12
Step-by-step explanation:
Given:3x+y=6
Value of
6x+2y=12
Since is the result of the equation 3x+y multiply by 2
Y8=40

Answer: -13w - 7
Step-by-step explanation:
-6w + (-8) + 1 + (-7w)
Combine the like terms
-8 + 1 = -7
-6w + (-7) + (-7w)
-6w + (-7w) = -13w
-13w + (-7)
However, because adding a negative number is the same as subtracting the number as a positive, you can just make it -13w - 7
