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 + 2(3d) 5d + 6d 11d
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
5d + 2(3d) 5d + 6d 11d
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) = ...
