<u>Question</u> :-
- Seven times the opposite of a number is 50 less than 3 times the number. What is the number?
<u>Explanation</u> :-
According to the question, it's given –
Seven times the opposite of a number is 50 less than 3 times the number.
We've assumed that the number is x. So, opposite of the number will be -x.
![\qquad](https://tex.z-dn.net/?f=%5Cqquad)
![\pink{ \bf \longrightarrow 7(-x) = 3x-50}](https://tex.z-dn.net/?f=%5Cpink%7B%20%5Cbf%20%20%5Clongrightarrow%207%28-x%29%20%3D%203x-50%7D%20)
Now, let's solve this equation –
![\qquad](https://tex.z-dn.net/?f=%5Cqquad)
![\bf \longrightarrow 7(-x) = 3x-50](https://tex.z-dn.net/?f=%20%5Cbf%20%20%5Clongrightarrow%207%28-x%29%20%3D%203x-50%20)
![\qquad](https://tex.z-dn.net/?f=%5Cqquad)
![\sf \longrightarrow -7x = 3x -50](https://tex.z-dn.net/?f=%20%5Csf%20%20%5Clongrightarrow%20-7x%20%3D%203x%20-50)
Subtract 3x from both side –
![\qquad](https://tex.z-dn.net/?f=%5Cqquad)
![\sf \longrightarrow -7x -3x = 3x -50-3x](https://tex.z-dn.net/?f=%20%5Csf%20%20%5Clongrightarrow%20-7x%20-3x%20%3D%203x%20-50-3x%20)
Cancel 3x from right side –
![\qquad](https://tex.z-dn.net/?f=%5Cqquad)
![\sf \longrightarrow -7x -3x =\cancel{ 3x} -50-\cancel{3x }](https://tex.z-dn.net/?f=%20%5Csf%20%20%5Clongrightarrow%20-7x%20-3x%20%3D%5Ccancel%7B%203x%7D%20-50-%5Ccancel%7B3x%20%7D)
![\qquad](https://tex.z-dn.net/?f=%5Cqquad)
![\sf \longrightarrow -10x = -50](https://tex.z-dn.net/?f=%20%5Csf%20%20%5Clongrightarrow%20-10x%20%3D%20-50)
Now, cancel (-) sign from both side –
![\qquad](https://tex.z-dn.net/?f=%5Cqquad)
![\sf \longrightarrow \cancel{-}10x = \cancel{-}50](https://tex.z-dn.net/?f=%20%5Csf%20%20%5Clongrightarrow%20%5Ccancel%7B-%7D10x%20%3D%20%5Ccancel%7B-%7D50)
![\qquad](https://tex.z-dn.net/?f=%5Cqquad)
![\sf \longrightarrow 10 x = 50](https://tex.z-dn.net/?f=%20%5Csf%20%20%5Clongrightarrow%2010%20x%20%3D%2050)
Then, divide both sides by 10 –
![\qquad](https://tex.z-dn.net/?f=%5Cqquad)
![\sf \longrightarrow \dfrac{10x}{10} = \dfrac{50}{10}](https://tex.z-dn.net/?f=%20%5Csf%20%20%5Clongrightarrow%20%5Cdfrac%7B10x%7D%7B10%7D%20%3D%20%5Cdfrac%7B50%7D%7B10%7D)
![\qquad](https://tex.z-dn.net/?f=%5Cqquad)
![\sf \longrightarrow \dfrac{\cancel{10}x}{\cancel{10}} = \cancel{\dfrac{50}{10}}](https://tex.z-dn.net/?f=%20%5Csf%20%20%5Clongrightarrow%20%5Cdfrac%7B%5Ccancel%7B10%7Dx%7D%7B%5Ccancel%7B10%7D%7D%20%3D%20%5Ccancel%7B%5Cdfrac%7B50%7D%7B10%7D%7D)
![\qquad](https://tex.z-dn.net/?f=%5Cqquad)
![\pink{ \bf \longrightarrow x = 5 }](https://tex.z-dn.net/?f=%5Cpink%7B%20%5Cbf%20%20%5Clongrightarrow%20x%20%3D%205%20%7D)
- Henceforth, the number will be 5.
