Question
Solve the equation by trial and error method: $3m – 14 = 4$
✓
Answer
| $L.H.S.$ | Value of $m$ | Value of $L.H.S.$ | $R.H.S.$ |
| $3m – 14$ | $0$ | $–14$ | $4$ |
| $3m – 14$ | $1$ | $–11$ | $4$ |
| $3m – 14$ | $2$ | $–8$ | $4$ |
| $3m – 14$ | $3$ | $–5$ | $4$ |
| $3m – 14$ | $4$ | $–2$ | $4$ |
| $3m – 14$ | $5$ | $1$ | $4$ |
| $3m – 14$ | $6$ | $4$ | $4$ |
So, $m = 6$ is the solution of the given equation $3m – 14 = 4.$
