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 =
Fourth, simplify

to 5. / Your problem should look like: x = 5
Answer:
x = 5
