Answer:
y = 3x + 23 and

Step-by-step explanation:
The first equation is 9x - 3y = - 69 and we have to write it in slope-intercept form.
Now, 9x - 3y = - 69
⇒ 3x - y = - 23 {Dividing both sides by 3}
⇒ 3x + 23 = y
⇒ y = 3x + 23 {Interchanging the sides} (Answer)
The second equation is x - 3y = - 6 and we have to write it in slope-intercept form.
Now, x - 3y = - 6
⇒ x + 6 = 3y
⇒ 3y = x + 6 {Interchanging the sides}
⇒
{Dividing both sides by 3}

Hello! The first thing you want to do is subtract 88 from 71 which gives you 17. If you multiply the belts times 71 that gives you 11,360. So then you have 17 left and all you do is multiply the shoe cost by 17 and that gives you 7,905. If you add 11,360+7,905 that gives you 19,265. So the correct answer would be 71!
I hope this helped!
