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!
4e + 3d + 5e - 5d = 9e - 2d
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
The expression is 5d+2c and the unknown variables are d and c
9/12
c - 5d = 2 2c + d = 4 Multiply eqn 1 by 2: 2c - 10d = 4 Subtract this from eqn 2: 0c + 11d = 0 which implies that d = 0 Then, by eqn 1, c = 2
4e + 3d + 5e - 5d = 9e - 2d
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
It can be simplified to: 14d+19e
Do you mean: 11d +1 = 5d+49? If so: 11d+1 = 5d+49 11d-5d = 49-1 6d = 48 d = 8
5d+3d = 15 8d = 15 d = 15/8 = 1.875
ac-5ad-5bc+25bd = a (c-5d) + 5b (c+5d) = ...
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.
