Question 65605
QUESTION;


Find b :

a/m = c(1/x + b/y)


ANSWER:




a/m = c(1/x + b/y)



Divide both sides by c Because here 'c' is multilying with the other term)



==> a/cm = (c/c)(1/x + b/y)



==> a/cm = (1)(1/x + b/y)



==> a/cm = (1/x + b/y)



We can write it as,



 a/cm = 1/x + b/y



Here we have to find out the valur of 'b', so shift all the terms except the term comtaining b to the other side.


==>   a/cm -1/x  =  b/y


Now multiply both sides by 'y' ( because here b is divided by y )


==> y ( a/cm -1/x )= (y) b/y


==>   ya/ cm -y/x  =  b



So the value of  b = y(a/ cm -1/x )
