3(x - 4) = 18, what is the value of x?

$$10$$

Explanation

First, distribute 3:
3(x - 4) = 18
$$3(x)-(3 \times 4)=18$$
3x – 12 = 18.
Next, isolate 3x by adding 12 on both sides:
3x = 18 + 12.
3x = 30
Finally, Divide both side by 3 to find the value of x:

$$\frac{3\text{x}}{3}=\frac{30}{3}$$
3x/3 = 30/3
x = 10
