Find the value of $V$:
$$25\times 18-660÷30=3V+14$$

Let's simplify the left-hand side of the equation step-by-step using BODMAS rules:
$$25\times 18-\frac{660}{30}=3V+14$$

1. Division first:

$$\frac{660}{30}=22$$

2. Multiplication next:

$$25\times 18=450$$

3. Re-assemble and subtract:

$$450-22=3V+14$$

$$428=3V+14$$

4. Solve the linear equation for $V$:

$$3V=428-14$$

$$3V=414$$

$$V=\frac{414}{3}=138$$
