Question

In the equation ab – c = d + ae, find
(a) d in terms of b, c, d and e
(b) b in terms of a, c, d and e

Answer 1

$Given \: eqution \: ab - c= d + ae$

$i) d + ae = ab - c$

$\implies d = ab - c - ae \\( d \: in \: terms \: of \:b,c,d \: and \: e )$

$ii ) ab - c = d + ae$

$\implies ab = d + ae + c$

$\implies b = \frac{ d + ae + c }{a} \\(b \: in \: terms \: of \:a,c,d \: and \: e )$
