The sum of two consecutive integers is –49. Write an equation that models this situation and find the values of the two integers

1 answer

Let the first integer be \( x \). Since the integers are consecutive, the next integer will be \( x + 1 \).

According to the problem, the sum of these two integers is \(-49\). Therefore, we can write the equation:

\[ x + (x + 1) = -49 \]

Simplifying the left side, we have:

\[ 2x + 1 = -49 \]

Next, we will isolate \( x \) by subtracting 1 from both sides:

\[ 2x = -49 - 1 \] \[ 2x = -50 \]

Now, divide both sides by 2:

\[ x = -25 \]

Now that we have the value of the first integer, we can find the second integer:

\[ x + 1 = -25 + 1 = -24 \]

Thus, the two consecutive integers are:

\[ -25 \quad \text{and} \quad -24 \]

In conclusion, the two consecutive integers are \(-25\) and \(-24\).
