Algebra dictionary definition:

Question 22

The sum of 3 numbers is 2n + 15. One of the numbers are 12. The other two numbers are equal. Express the second number in terms of n.

First, separate the n's and the normal numbers.

Step 1: Simplify

​2n

​15

Twelve is one of the numbers. You are trying to find the other two numbers and this equation is the total of all numbers so...

Step 2: The 12

​2n

​15

​-12

​= The total of the 2 equivalent numbers

Now you have the total of the 2 equivalent numbers. To find one of the numbers (and since it's a duplicate number)...

Step 3: The Answer

​(2n + 3) ÷ 2

​= One of the duplicate numbers

​+

Step 4: Da advanced answer

​1n + 1.5

​+

Question 36

Isi has 760 rambutan and durian trees altogether at first. She cut down 1/4 of the rambutan trees and planted 50 more durian trees. Now she has 6 times more durian trees than rambutan trees. How many more rambutan trees did she have first?

Let's draw this out on a graph...

In total...

​In total, there are 770 because of the 50 and counting the ones that have been cut down

For the next step, you have to guess how many each square is. To make things simpler for you, it's 90.
