​

Answer 1

47

Explanation:

3068 - 1266 - 1755 = 47

Answer 2

The third number is 47.

Explanation:

The sum of three numbers is 3068 - this can be expressed mathematically as:

`\displaystyle{x + y + z = 3068}`

Given that two of the numbers are 1266 and 1755 (in order) then substitute x = 1266 and y = 1755:

`\displaystyle{1266 + 1755 + z = 3068}`

Find the third number - solve for z-variable:

`\displaystyle{3021 + z = 3068}\\\\\displaystyle{z = 3068-3021}\\\\\displaystyle{z = 47}`

Therefore, the third number is 47.
