Question

the sum of three integers you is (-521) if two integers are 198 and (-221) find the third integers.​

Answer 1

Answer:

-498

Step-by-step explanation:

Let the third integer be 'x'

198 + (-221) + x = -521

198 - 221 + x = -521

-23 + x = -521

x = -521 + 23

x = -498

∴ The third integer is  -498.

Answer 2

Answer:

sum of 3 integers =(-521)

1st integer=198

2nd integer=(-221)

3rd integer=(-521)-[198+(-221)]

=(-521)-(-23)

= (-521)+23

=(-498)
