  x = 2

Step-by-step explanation:

This linear equation has 1 answer. It can be found by working backward through the operations that are performed on the variable. Those are ...

We can "undo" the last of these by adding 2 to both sides of the equation.

  3(x +4) = 18

Undo the multiplication by 3 by dividing both sides by 3.

  x +4 = 6

Undo the addition of 4 by adding -4.

  x = 2 . . . . . the solution

Check

Put 2 in the equation where x is and see if it is true.

  3(2 +4) -2 = 16

  3(6) -2 = 16

  18 -2 = 16 . . . . . true
