Subtract 4 from both sides to get 3x = 15.

Divide by 3 on both sides to get x = 5.

Plug this back in.

3(5) + 4 = 19.
15 + 4 = 19.
19 = 19

3x + 4 = 19

Take away 4 from both sides:
3x = 15

Divide both sides by 3:
x = 5

Answer: x = 5

To check, we plug x = 5 into the equation:
3x + 4 = 19
3(5) + 4 = 19
19 = 19 (✓ correct)
