Without further information, all we can do is simplify:
4c + 4d = 4(c + d)
3c - 4d = 6d + 4c Subtract 4c from both sides: -c - 4d = 6d Add 4d to both sides: -c = 10d or c = - 10d
4d + 7 = -15 so 4d = -22 so that d = -5.5

4d is time...any moving object is 4d
2-4d = -2
3c - 4d = 6d + 4c Subtract 4c from both sides: -c - 4d = 6d Add 4d to both sides: -c = 10d or c = - 10d
4d + 7 = -15 so 4d = -22 so that d = -5.5
14d + 20e
4c4d is equivalent to 16cd.
It is an equation and the value of d is 2
d = 2
8 - 4d = 12-4d = 4d = -1
4d-2 equals 6b-4
The equation 3 + 4d = 39 can be solved by subtracting 3 from both sides, resulting in 4d = 36. Then, divide both sides by 4 to find that d = 9.

4(9)-11=25 2(9)+7=25 d=9
Unfortunately, due to the limitations of browsers, most mathematical symbols get removed and it leaves gibberish that is impossible to answer. Please edit/re submit your question with a full sentence of what you want solved, replacing mathematical symbols by words: plus for + equals for = etc.
