So your equation would be 8a+10=11d-6 First: you would combine like terms so normally you would take away the smaller number. So to cancel out the negative 6 you added you add positive six to the negative 6 so you would get 0 and whatever you do to one side you have to do to the other so you would do 10 + 6. Your new equation would be 8a+16=11d. Now you do -16 to both sides. So your new equation would be 8a= 11d - 16. Now you divide by 8. So your final equation would be a=11d-2.

Answer:


a=(11d-16)/(8)

Explanation:

We have been given a word phrase. We are asked to write an equation and solve for 'a'.

Eight times the number 'a' would be
8a.

Ten plus eight times a number 'a' would be
10+8a.

Eleven times another 'd' would be
11d.

Eleven times another 'd' minus six would be
11d-6.

Equate both expression:


10+8a=11d-6


10-10+8a=11d-6-10


8a=11d-16


(8a)/(8)=(11d-16)/(8)


a=(11d-16)/(8)

Therefore, the value of 'a' is
(11d-16)/(8).
