Write an equation to represent each relationship. Then solve the equation.

34. Three times the sum of a number and 4 is the same as 18 more than the number.

36. Two less than 2 times a number is the same as the number plus 64.

If we say "a number" is x, we can write the equations. "The sum of a number and 4" could be written as x+4. 3 times the sum of a number and 4 can be written as 3(x+4). When it says "is the same as", it's just saying it's equal to. So we can say that: 3(x+4)=18+x And that's your answer to #34

Let's say that "a number" is n this time. "2 times a number" can be written as 2n. 2 less than 2n is just saying 2n-2. Now we can get your answer: 2n-2=n+64

In Problem 34, the variable x is found to be 3. In Problem 36, the variable n is found to be 66. These solutions were derived by translating the given relationships into equations and solving them step-by-step.
