Answer:
3/1 or 3
Step-by-step explanation:
7 1/3 = 7x3 + 1/3 =21 + 1/3 =22/3
7x3/3 = 21/3
-------------------------------------------------
2 4/9 2x9 + 4/9 = 18 + 4 /9= 22/9
2x9/9 = 18/9
Divide: 22/3 : 22/9 =22/3 x9/22 =
22/3 x 9/22 = 198/66 66/66 x 3/1 = 3

We are given first equation y=
x+11.
Second equation is -3x + 7y = 13.
Part A: We need to convert that second equation in slope-intercept form y=mx+b.
In order to convert it in slope-intercept form, we need to isolate it for y.
-3x + 7y = 13
Adding 3x on both sides, we get
-3x+3x + 7y = 3x+13
7y = 3x +13.
Dividing both sides by 7, we get
7y/7 = 3x/7 +13/7.
<h3>y= 3/7 x + 13/7.</h3>
Slope for first equation y=3/7 x +11 is 3/7 and slope of second equation y= 3/7 x + 13/7 is also 3/7.
Slopes are same for both equations.
<h3>Part B: Therefore, lines are parallel due to equal slopes.</h3>
