OK. Start by multiplying both sides by \(2c\) to get rid of the denominator. So, we will have \(a+b=(b+d)2c\). Opening the parenthesis gives \(a+b=2bc+2cd\). Since we're trying to solve for \(b\), we should combine all terms with \(b\) in one side and everything else on the other side. That gives \(b-2bc=2cd-a\). Take \(b\) as a common factor in the left hand side, you get \(b(1-2c)=2cd-a\). Finally divide both sides by \(1-2c\) you get \(b=\frac{2cd-a}{1-2c}\).

b = (a-2*c*d)/(2*c-1)

cross multiply then a+b =2c(b+d) then take b containing term on one side and rest on other side so b(2c-1) = a-2cd now divide both side by (2c-1) so u get b= (a-2cd)/(2c-1)

(a+b)/2c = b=d 2bc + 2cd = a + b .................. (multiply both side by 2c) 2bc - b = a - 2cd ...................... (changing side of b) b ( 2c - 1) = a - 2cd b = (a-2cd) / (2c - 1)
