14d + 20e
d = 2
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
D + 3D = 240 4D = 240 Divide both sides of the equation by 4: D = 60
1.6-d=12.8+3d 12.8-1.6=-d-3d 11.2=-4d 11.2/-4=d d=-2.8
3c - 4d = 6d + 4c Subtract 4c from both sides: -c - 4d = 6d Add 4d to both sides: -c = 10d or c = - 10d
10d - 6 = 4d - 15 - 3d10d - 6 = d - 159d = -9d=-1
4d + 7 = -15 so 4d = -22 so that d = -5.5
It is an equation and the value of d is 2
d = 2
Without further information, all we can do is simplify: 4c + 4d = 4(c + d)
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
