3x - 4(4) = 65

First, simplify 4 × 4 to get 16. / Your problem should look like: 3x - 16 = 65
Second, add 16 to both sides. / Your problem should look like: 3x = 65 + 16
Third, simplify 65 + 16 to 81. / Your problem should look like: 3x = 81
Fourth, divide both sides by 3. / Your problem should look like: x = [tex] \frac{81}{3} [/tex]
Fifth, simplify [tex] \frac{81}{3} [/tex] to 27. / Your problem should look like: x = 27

Answer: x = 27
