Answer:

5x + 12

Explanation:

7x − (2x − 7) − (−6 + 1)

<u>Distribute the Negative Sign</u>

7x − (2x − 7) + −1(−6 + 1)

7x + −2x + 7 + (−1)(−6) + (−1)(1)

7x + −2x + 7 + 6 + −1

<u>Combine Like Terms</u>

7x + −2x + 7 + 6 + −1

(7x + −2x) + (7 + 6 + −1)

= 5x + 12

Hence, -45 is the number which when added to the given fraction will give 2/3

Further explanation:

Given fraction is:

$\frac{23}{12}$

Let x be the number which has to be added to numerator and denominator

Then

$\frac{23+x}{12+x}=\frac{2}{3}$

Cross-multiplying

$\frac{23+x}{12+x}=\frac{2}{3} \\3(23+x)=2(12+x)\\69+3x=24+2x\\3x-2x=24-69\\x=-45$

Hence, -45 is the number which when added to the given fraction will give 2/3
