Hello,

To solve this question you can start by listing each country.

Country A = A

Country B = B

You then know that Country A has 5855 more universities. This means that you add 5855 to Country B to get country A. More means add. This would look as follows:

Country A = Country B + 5855.

Now you have:

Country B = B

Country A = B + 5855

The question says the total is 14165 which means Country A + Country B is 14165 or:

B + (B + 5855) = 14165

You can now simplify and solve.

B + (B + 5855) = 14165

2B + 5855 = 14165

**combine like terms

2B + 5855 = 14165

- 5855 - 5855**Subtract from both sides to get B by itself.

2B = 8310

/2 /2

** Divide both sides by 2 to get rid of the 2 and get B by itself.

B = 4155

Now you know what B is and can input the values.

Country B = B = 4155

Country A = B + 5855 = (4155) + 5855 = 10010

Country A = B + 5855 = (4155) + 5855 = 10010

Country B = 4155

Country A = 10010

Country A = 10010

Total = 14165.

You can add the two numbers together to check your answer and you should get 14165.
