Write an equation for the following:

"Three times the sum of a number and four is the same as eighteen more than the number."

Answer: 3 (x+4) = x+18

Step-by-step explanation: Break down the problem. It says three times the sum of a number and 4. You have to add the number and 4 first. Since you're multiplying by 3, put the sum of a number and 4 in parentheses. This equals the same as eighteen more than the number. It set up how it sounds. Add 18 to the number.
