Question

The sum of six times a number and 11 is 77. Find the number​

Answer 1

the number is 11

Explanation:

let the number be n then 6 times the number is 6n

the sum of 6n and 11 is 6n + 11 , then equate to 77 , that is

6n + 11 = 77 ( subtract 11 from both sides )

6n + 11 - 11 = 77 - 11 , that is

6n = 66 ( divide both sides by 6 )

`(6)/(6)` n =
`(66)/(6)` , then

n = 11
