Question
Solve the following equation and verify the answer: $x - 7 = 6$
✓
Answer
$x - 7 = 6$ Adding $7$ on both the sides:
$\Rightarrow x - 7 + 7 = 6 + 7 $
$\Rightarrow x = 13$
Verification: Substituting $x = 13$ in the $L.H.S. $
$\Rightarrow 13 - 7 = 6 = R.H.S. $
$L.H.S. = R.H.S$. Hence, verified.
$\Rightarrow x - 7 + 7 = 6 + 7 $
$\Rightarrow x = 13$
Verification: Substituting $x = 13$ in the $L.H.S. $
$\Rightarrow 13 - 7 = 6 = R.H.S. $
$L.H.S. = R.H.S$. Hence, verified.
