Question

I do not answer please help

Answer 1

276 guests

Explanation:

let the total number of guests be x , then

`(x)/(3)` +
`(5x)/(12)` + 69 = x

multiply through by 12 to eliminate the fractions

4x + 5x + 828 = 12x

9x + 828 = 12x ( subtract 9x from both sides )

828 = 3x ( divide both sides by 3 )

276 = x

There are 276 guests at the wedding
