Answer:

8(11+x) = 123,

Where, x = unknown number

Step-by-step explanation:

Let x be the unknown number,

Since, Sum of 11 and x = 11 + x

Eight times of the sum of 11 and x = 8 × sum of 11 and x

= 8(11 + x)

According to the question,

Eight times of the sum of 11 and x = 123

⇒ 8(11+x) = 123

Which is the required equation.
