Question

Bc-ad = 3c+r solve forc

Answer 1

`c = (r+ ad)/(b - 3)`

Explanation:

`\begin{array}{rcll}bc - ad& = & 3c + r &\\bc - 3c - ad & = & r & \text{Subtracted 3c from each side}\\bc - 3c & = & r + ad & \text{Added ad to each side}\\c(b - 3) & = & r + ad &\text{Removed the common factor} \\\mathbf{c} & = & \mathbf{(r+ ad)/(b - 3)} &\text{Divided each side by (b - 3)} \\\end{array}`
