Question

The sum of two numbers is negative twenty-three. One number is seven less than the other. Find the numbers.

Answer 1

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.

Answer 2

Answer:

Step-by-step explanation:

Let one no. =x

Therefore,other no. =x-7

According to question,

x+x-7= -23

2x=-23+7

x=-16/2

x=-8
