I WILL GIVE BRAINLIEST!! :D
STALIN [3.7K]

Answer:

The number in the middle is 60.

Step-by-step explanation:

The 2nd number = A

The 3rd number = B

The 4th number = C

Given:

(1) 130 + A + B = 300

(2) A + B + C = 200

(3) B + C + 10 = 100

Now, the work:

(2) can be modified to become A + B = 200 - C

Now, we can insert that into (1) and get the following;

130 + (200 - C) = 300

Open parentheses, simplify, you get C = 330 - 300.

C = 30

Using (3), we use above answer to get B + 30 + 10 = 100

Calculate, and get B = 100 - (30 + 10)

Simplify,

B = 60

There is your answer!

Cheers
