Let x be the number.

Given the statement: Three sets of a sum of a number and four are added to the sum of seven times the same number and thirteen.

" sum of a number and four" translated to x + 4

"Three sets of a sum of a number and four" translated to 3(x+4)

"sum of seven times the same number and thirteen" translated to 7x + 13

then;

the expression for the given statement become;

`3(x+4) + 7x + 13`

Using distributive property:
`a\cdot (b+c) = a\cdot b + a\cdot c`

`3x +12 + 7x+ 13`

Combine like terms;

`10x + 25`

Therefore, the simplified expression for Three sets of a sum of a number and four are added to the sum of seven times the same number and thirteen. is,
`10x + 25`
