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.

How do I do these? I don't understand them. Please explain them.

Sagot :

34. 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

36. 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
