Q. The sum of 3 integers in 15. of two of the integers are (−11) and 7 , find the third integer.
Calculate Sum and Subtract: To find the third integer, we need to add the two known integers and subtract their sum from the total sum of 15. Calculation: 15−(−11+7)
Add Known Integers: First, add the two known integers, −11 and 7.Calculation: −11+7=−4
Subtract Sum from Total: Next, subtract the sum of the two known integers from the total sum of 15 to find the third integer.Calculation: 15−(−4)=15+4=19
Find Third Integer: The third integer is therefore 19.
