Let's keep the,

Value of unknown number as y.

Then find the y,

→ 5y + 30 = 15

→ 5y = 15 - 30

→ 5y = -15

→ y = -15/5

→ [y = -3]

Therefore, -3 is the number.

Answer:

<em>Natalie's total spread = 18</em>

Step-by-step explanation:

The 'spread' of a crossword puzzle tournament player is computed as his/her total score minus the opponent's total score.

Natalie's scores are:

N=410+380+395+370+320+360=2,235

Opponent's scores are:

O=395+360+412+355+340+355=2,217

Natalie's total spread = 2,235 - 2,217 = +18

Natalie's total spread = 18
