First we substitute, what that means in here is that 2(c +3)
Or minus I can't see the sign but what we do is we substitute 2 with c so that becomes 2c and 2 with 3 and that becomes 6 which gives us 2c + 6 = c-13
Now we can either add 13 on both sides or subtract 6 on both sides, we can do this because they are like terms even if they are negative because they don't have any variable behind it. We will add 13 because we do the opposite of the sign you are solving some get 2c + 19 = c now we subtract 2c on both sides and we get 19 = -1c and at the end we divide -1 on both side and we get -19 = c or
c = -19.

Step-by-step explanation:
other will answer it
So she has

cups of yogurt for making fruit parfaits, and each parfait requires

cup of yogurt. This would imply that we would have to divide the first fraction by the second fraction to find out how many parfaits she can make.
Skip, switch, flip (I believe that's how the statement goes?) When you are dividing a fraction, you skip the first fraction, switch the division sign into a multiplication sign, and flip the second fraction so the denominator is the numerator, and the numerator is the denominator. That would make it :

×

: And 14 × 6 is 84, and 6 times 2 is 12. That would mean that we divide

.
84 divided by 12 is 7. She can make
7 parfaits.
First term, n=1: 2*1 -3 = -1
Second term, n=2: 2*2 -3 = 1
Third term, n=3: 2*3 -3 = 3
