If -6d = 42 then 6d = -42. then divide by 6, d = -7
If: a = b+c+d Then: c = a-b-d
72-6d=6 subtract 72 from both sides -6d=66 divide by -6 d=-11
c= (a+d) / 2b
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
If -6d = 42 then 6d = -42. then divide by 6, d = -7
If: a = b+c+d Then: c = a-b-d
72-6d=6 subtract 72 from both sides -6d=66 divide by -6 d=-11
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
Divide both sides by 4: c = d/4
c= (a+d) / 2b
(a+d)/2b=c
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
C= pi * D This is the formula for circumference.
It is an equation and the value of d is 2
Type your answer here... a = 2bc-d add d to both sides a + d = 2bc divide both sides by 2b (a+d)/2b = c
A = 2bc - dAdd 'd' to each side of the equation:A + d = 2bcDivide each side by 2b :(A + d)/2b = c
