3x + 3 = 18
First, subtract 3 from both sides. / Your problem should look like: 3x = 18 - 3
Second, simplify 18 - 3 to 15. / Your problem should look like: 3x = 15
Third, divide both sides by 3. / Your problem should look like: x = [tex] \frac{15}{3} [/tex]
Fourth, simplify [tex] \frac{15}{3} [/tex] to 5. / Your problem should look like: x = 5
Answer: x = 5
