Answer:

x = 10

Step-by-step explanation:

We would use postulates and theorem to figure out 34 = 3x + 4. Once you set 34 equal to 3x + 4, you would solve for x as can be shown below:

34 = 3x + 4

Subtract 4 from both sides.

30 = 3x

Divide both sides by 3.

10 = x

Answer:

10

Step-by-step explanation:

(3x + 4)° = 34°

x = 10
