Answer:
<h2>Pete played 1.5 times the number of matches that Jack played.</h2><h2 />
Step-by-step explanation:
<u>Pete played 18 tennis matches in a week.</u>
P = 18
<u>Jack played 6 fewer matches than Pete. </u>
J = P - 6
J = 18 - 6
J = 12
<u>How many times the number of matches pete played is the number of matches jack played?</u>
<u />
18 / 12 = 1.5
Pete played 1.5 times the number of matches that Jack played.

I would solve the first equation for x and then sub that value into x in the second equation.  That's the easiest way.  x - 2y = 3 solved for x is x = 2y+3.  Now sub that in for x in the second equation: 5(2y+3)+3y=2 and 10y + 15 + 3y = 2.  13y = -13, and y = -1.  Now sub that y value into either equation to solve for x: x = 2(-1) + 3 gives us an x value of x = 1.  Therefore, your solution to this system is (1, -1), first choice above.
