Question
Solve the equation and check your result: $5x + 9 = 5 + 3x$
✓
Answer
$5x + 9 = 5 + 3x$
$5x –3x = 5 – 9 ... [$Transposing $3x$ to $L.H.S.$ and $9$ to $R.H.S]$
$\therefore 2x = –4$
$\therefore x = - \frac{4}{2} ... [$Dividing both sides by $2]$
$\therefore x = –2$ this is the required solution.
Verification
$L.H.S. = 5(–2) + 9 = – 10 + 9 = –1$
$R.H.S. = 5 + 3(–2) = 5 – 6 = –1$
Therefore, $L.H.S = R.H.S$
$5x –3x = 5 – 9 ... [$Transposing $3x$ to $L.H.S.$ and $9$ to $R.H.S]$
$\therefore 2x = –4$
$\therefore x = - \frac{4}{2} ... [$Dividing both sides by $2]$
$\therefore x = –2$ this is the required solution.
Verification
$L.H.S. = 5(–2) + 9 = – 10 + 9 = –1$
$R.H.S. = 5 + 3(–2) = 5 – 6 = –1$
Therefore, $L.H.S = R.H.S$
