Question
Solve the equation and check your result: $3x = 2x + 18$
✓

Answer

$3x = 2x + 18$
$3x – 2x = 18 ... [$Transposing $2x$ to $L.H.S]$
$\therefore x = 18$ this is the required solution.
Verification,
$L.H.S. = 3x = 3 \times 18 = 54$
$R.H.S. = 2x + 18 = 2 \times 18 + 18 = 36 + 18 = 54$
Therefore, $L.H.S = R.H.S$
