Oh, dude, you want me to do math? Alright, so in the expression 5d + 2c, "5" and "2" are the coefficients, and "d" and "c" are the variables. So, like, the variables are "d" and "c," and the numbers are 5 and 2. That's it, that's the math lesson for today.

In the expression 5d + 2c, "5" and "2" are the numerical coefficients of the variables "d" and "c," respectively. The variables "d" and "c" are the unknown quantities that can take on different values. The expression represents the sum of five times the value of "d" and two times the value of "c."
Well, isn't that just a happy little math problem we have here? In this expression, "5d" and "2c" are our variables, which are letters that represent unknown numbers. We can't simplify this expression any further without knowing the specific values of "d" and "c," but we can add or subtract them if we have those values. Just remember, there are no mistakes in math, only happy little accidents!
Need your help for answer
8d = 5d+18 8d-5d = 18 3d = 18 d = 6
5d + 19 = 79 ````-19` -19 5d = 60 `/5` /5 d=12
5d+3d = 15 8d = 15 d = 15/8 = 1.875
2(3d+7)=5+5d. 6d+14=5+5d 6d+9=5d 9=-1d d=-9 I think that's correct. If it is, ur welcome.
