You solve an equation like this by adding the opposite of the constant to both sides of the equation.
... V -16 +16 = -32 +16 . . . . . addition property of equality: if a=c, then a+b = c+b
... V + 0 = -16 . . . . . . . . . . . . additive inverse property of integers: -16+16 = 0
... V = -16 . . . . . . . . . . . . . . . identity element of addition: V+0 = V
_____
<em>You can always do the same thing to both sides of an equation.</em> Here, it is useful to add the opposite of -16 to both sides. That way the constant on the left becomes zero, so you only have the variable by itself—which is what you want.
Answer:
Step-by-step explanation:
In the first column, put days at the top and pounds at the bottom.

Answer:
Card 7
Step-by-step explanation:
2+5+7+8+9 =31
Multiples of 6: 6, 12, 18, 24, 30
31-9=22, No
31-8=23, No
31-5=26, No
31-2=29, No
31-7=24, Yes
The only way to get a multiple of 6 is to subtract card 7, so card 7 is the answer.
