What is -6d equals -42?
-6d = -42-6(7) = -42d = 7
What is d plus 3d plus 6d?
They can be simplified to 10d
What is 3d plus 7 equals 6d plus 5?
3d+7=6d+5 The first thing would be to subtract 3d from both sides. You will end up with 7=6d-3d+5. Then subtract 5 from both sides. Now you have 7-5=6d-3d. Now you have the numbers with like terms on either side of the equation. 7-5=2 and you can subtract 3d from 6d because both 6 & 3 have d as their variable. So 6d-3d=3d. Now the equation is 2=3d. Now you have to divide both sides by 3. (Since 3d is also expressed as 3 x d, we need to do the opposite of multiplication which is division, in order to get the variable d by itself) So now you have 2/3=d, or d is two thirds.
6d-3d plus 2d equals 35 what is the unknown?
To solve the equation 6d - 3d + 2d = 35, we first combine like terms on the left side. This gives us 5d + 2d = 35. Combining like terms further, we get 7d = 35. To find the value of the unknown variable "d," we divide both sides by 7, resulting in d = 5.
How do you solve this problem 5d-4 equals 4-d?
5d-4=4-d you have to bring the d to one side and the 4 to the other remember there is a 1 in front of the d so you'll get 6d-4=4 then you get 6d=8 then you divide and get d=4/3 or 1 and 1/3
