Without further information, all we can do is simplify: 4c + 4d = 4(c + d)
4d + 7 = -15 so 4d = -22 so that d = -5.5
4d is time...any moving object is 4d

Hi
Group 5c-2c and 7d-3d and it comes to 3c+4d
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
It is a linear equation in one unknown, d.
4(9)-11=25 2(9)+7=25 d=9
