Respuesta :
2 + n = 7/8n - 15
2 + n - 7/8n = 7/8n - 7/8n - 15
2 + 1/8n = - 15
2 - 2 + 1/8n = - 15 - 2
1/8n = - 17
n = - 136
2 + n - 7/8n = 7/8n - 7/8n - 15
2 + 1/8n = - 15
2 - 2 + 1/8n = - 15 - 2
1/8n = - 17
n = - 136
Answer: The required number is -136.
Step-by-step explanation: Given that two more than a certain numbers 15 less than the product of [tex]\dfrac{7}{8}[/tex] and the number.
We are to find the number.
Let the required number be represented by x.
Then, according to the given information, we have
[tex]x+2=\dfrac{7}{8}x-15\\\\\\\Rightarrow x+17=\dfrac{7}{8}x\\\\\\\Rightarrow 8x+136=7x\\\\\Rightarrow 8x-7x=-136\\\\\Rightarrow x=-136.[/tex]
Thus, the required number is -136.
