If -6d = 42 then 6d = -42. then divide by 6, d = -7
9d-19=6d+2 ... add 19 to both sides and subtract 6d from both sides... 9d-6d=2+19 3d=21 d=21/3 d=7
9d+3
2(3d+7)=5+5d. 6d+14=5+5d 6d+9=5d 9=-1d d=-9 I think that's correct. If it is, ur welcome.
5d + 2(3d) 5d + 6d 11d
If -6d = 42 then 6d = -42. then divide by 6, d = -7
9d-19=6d+2 ... add 19 to both sides and subtract 6d from both sides... 9d-6d=2+19 3d=21 d=21/3 d=7
2(d^2 + 6d - 8)
9d+3
2(3d+7)=5+5d. 6d+14=5+5d 6d+9=5d 9=-1d d=-9 I think that's correct. If it is, ur welcome.
you need 2
5d + 2(3d) 5d + 6d 11d
-6d = -42-6(7) = -42d = 7
It is an equation and the value of d is 2
72-6d=6 subtract 72 from both sides -6d=66 divide by -6 d=-11
yes you can
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.
