\(5x + 9 = 5 + 3x\)
On transposing \(3x\) to L.H.S and \(9\) to R.H.S, we obtain
\(5x - 3x = 5 - 9\)
\(2x = -4\)
On dividing both sides by \(2\), we obtain
\(x = -2\)
\(\Rightarrow\) L.H.S \(= 5x + 9\)
=\(5 \times (-2) + 9\)
= \(-10 + 9\) \(= -1\)
\(\Rightarrow\) R.H.S \(= 5 + 3x = 5 + 3 \times (-2)\)
= \(5 - 6 = -1\)
L.H.S. = R.H.S.
Hence, the result obtained above is correct.
