Step-by-step explanation:
3x-y=7
2x-2y=2
------------
y=3x-7
substitute this equation to 2x-2y=2
first, simplify 2x-2y=2 into x-y=1.
-----------------------------------------------------
x-(3x-7)=1
x-3x+7=1
-2x+7=1
-2x=1-7
-2x=-6
x=-6/-2=3
y=3(3)-7=9-7=2
Answer: x=3, y=2.

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
