Question :
- Six times a number is 14 less than the opposite of that number. What is the number?
Solution :
Let's assume the number as " x "
According to the question :
- Six times a number is 14 less than the opposite of that number.
We already assumed that the number is x. So, opposite of the number would be -x.
![\qquad \sf \: { \dashrightarrow 6x= - x-14}</p><p>](https://img.qammunity.org/2023/formulas/mathematics/high-school/5iv4ki6vqqxt8omti2fynwri7n8ga2o87g.png)
Now, let's solve this equation :
![\qquad \sf \: { \dashrightarrow 6x + x= -14}</p><p>](https://img.qammunity.org/2023/formulas/mathematics/high-school/b26ntlf0xq9avkikxz16oh5pe30jt9vvym.png)
Combining the like terms :
![\qquad \sf \: { \dashrightarrow 7x = - 14}</p><p>](https://img.qammunity.org/2023/formulas/mathematics/high-school/bn2kcgq1k3m8i1g25q0cev2c3m5x658dvs.png)
Then divide both sides by 7 :
![\qquad \sf \: { \dashrightarrow (7x)/(7) = - (14)/(7) }</p><p>](https://img.qammunity.org/2023/formulas/mathematics/high-school/g8efpv4230r9oufcqizfhe3h9h5ugnfldf.png)
![\qquad \sf \therefore \: \bf{{ x= -2}}</p><p>](https://img.qammunity.org/2023/formulas/mathematics/high-school/36oq6zn7na9w9rzyhkhkxvv8x74lgorpki.png)
Therefore, the required number is -2 .
