Answer:
first number −8 second number −15
Step-by-step explanation:
n+n−7=−23
Combine like terms.
2n−7=−23
Add 7 to each side and simplify.
2n=−16
Divide each side by two and simplify.
n=−8
Now solve for each number.
n−8−=−8 1st number
n −7 2nd number
-8−7
-15
Step 6. Check. Is −15 seven less than −8?
−8−7−=-15
−15=−15✓
Is their sum −23?
−8+(−15)=−23
−23=−23✓
Step 7. Answer the question.
The numbers are −8 and −15.
