Answer 1

$\bold{Given :} \\ \\ = = > 4r - 41 = 89 \\ \\ \bold{To \: find :} \\ \\ Value \: of \: r \\ \\ </p><p></p><p></p><p> \bold{Solution :} \\ \\ = = > 4r - 41 = 89 \\ \\ = = > 4r = 89 + 41 \\ \\ = = > 4r = 130 \\ \\ = = > r = \frac{130}{4} \\ \\ = = > r = \cancel\frac{130}{4} \\ \\ = = > r = \frac{65}{2} \\ \\ = = > \bold{r = 32.5}\\ \\ Therefore \: \bold\red{ r = 32.5 }\\ \\ \bold{Verification :} \\ \\ = = > 4r - 89 = 41 \\ \\ = = > 4(32.5) - 89 = 41 \\ \\ = = > 130 - 89 = 41 \\ \\ = = > 41 = 41 \\ \\ = = > L.H.S = R.H.S \\ \\ </p><p></p><p></p><p>Hence \: \bold \blue{32.5} \: is \: the \: valid \: answer.</p><p>$
