The method used is usually to isolate the value being solved for on the left hand side of the equation
so, when we are told that
a = 2bc - d
we switch the equation around and get
2bc - d = a
Then we add 'd' to each side and get
2bc = a + d
Then we divide both sides by '2b' and get
c = (a + d) / 2b
d=a-2bc
d = a - 2bc
(a+d)/2b=c
Not sure about the original formula, but one that works is b = a/(2c + 1)
d = a - 2bc
d=a-2bc
Type your answer here... a = 2bc-d add d to both sides a + d = 2bc divide both sides by 2b (a+d)/2b = c
d = a - 2bc
d = a - 2bc
If a=2bc+db= (a - d) / 2c If a=2b+c b=1/2(a-c)
(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
Not sure about the original formula, but one that works is b = a/(2c + 1)
c= (a+d) / 2b
d = a - 2bc
No. 1a and 3d are linear, but 2bc is not. ■
None.
