Hi, I have been trying to get my head around simplifying equations and was doing ok until I met this one:
(a+bx)/cx=d+5 Im trying to solve for x and it's cx thats my brick wall. Would someone be kind enough to guid me through it please.?

Hello, nejuleho!
$\displaystyle \text{Solve for }x:\;\;\frac{a+bx}{cx} \:=\:d+5$
$\displaystyle \begin{array}{ccccc}\text{Multiply by }cx: & a+ bx \:=\:cx(d+5) \\ \\ \text{Expand:} & a+bx \:=\:cdx + 5cx \\ \\ \text{Subtract }bx: & a \:=\:cdx + 5cx - bx \\ \\ \text{Factor:} & a \:=\:(cd + 5c - b)x \\ \\ \text{Therefore:} & \dfrac{a}{cd+5c-b} \:=\:x \end{array}$
