6d-12-d = 9d+53+d

6d-d-9d-d = 53+12

-5d=65
Change the signs: 5d= -65 The negative becomes positive and vice versa

5d/5=d and -65/5= -13
d= -13

Check: Remember a negative times a negative makes a positive.
6d-12-d = 9d+53+d
-78-12-(-13) = -117+53-13
-78-12+13= -117+53-13
-90+13= -130+53
-77 = -77

I hope this helps.

By the way, you are not a retard!

First place all the d's to the left of the equation and all the rest to the right:

6d-d-9d-d=12+53 (You know that when you transpose from left to right and vice versa, you have the change the signs, right?)

Then simplify:

-5d=65

Then divide both sides by -5to solve for d:

-5d/-5=65/-5
d=-65/-5
d=-13

well this is what i got
6d - 12 - d = 9d + 53 + d
5d - 12 = 10 d + 53
+12 +12
5d = 10d + 65
-10d -10d
-5d= 65
d= -13

6d-12-d=9d+53+d

5d-12=10d=53

-12=5d+53

64=5d

d=-13

5d = 10d + 65
-5d = 65
d = -13

Interestingly enough, the 2 answers above that went into great detail (including the insulting "retard") both gave you the incorrect answer. It should be -13 and not 13.

2006-09-20 00:15:17 · answer #9 · answered by TheDude 3 · 1 0

combine the d's on both sides:
5d-12=10d+53

subtract 5d from both sides:
-12=5d+53

subtract 53 from both sides:
65=5d

divide both sides by 5:
13=d

flip it and you get:
d=13
