Answer» Solution:-━━━━━━━━━━━━━━━━━━━━━━━━━━
ANSWER:-⇒ 2nd Integer is -45.. Option C is correct. GIVEN:-◦ Sum of 2 integers = -25 ◦ 1st integer = 20 TO FIND:-⟶ 2nd integer = ? FORMULA:-
SOLVING STEP BY STEP:-◦ Sum of 2 integers = -25 ◦ 1st integer = 20 ◦ 1st Integer + 2nd Integer = Total
» LET the 2nd integer be x. » 20 + x = -25 » Taking 20 to R.H.S. » x = -25 -20 » x = -45 Thus, we GOT the answer. The 2nd integer is -45. So, option C is correct. VERIFICATION:-⚩ 1st Integer = 20 ⚩ 2nd Integer = -45 ⚩ 20 + (-45) [ (+) + (-) = (-) ] ⚩ 20 - 45 ⚩ 20 - 45 = -25 ⚩ -25 Hence, verified. ━━━━━━━━━━━━━━━━━━━━━━━ |
