Just sub in ANY number for x and solve for y

5x + 7y = 19.....lets say x = 0
5(0) + 7y = 19
7y = 19
y = 19/7...so when x = 0, y = 19/7.....(0,19/7)

5x + 7y = 19....lets say x = 1
5(1) + 7y = 19
5 + 7y = 19
7y = 19 - 5
7y = 14
y = 14/7
y = 2.....so when x = 1, y = 2......(1,2)

5x + 7y = 19.....lets say x = 3
5(3) + 7y = 19
15 + 7y = 19
7y = 19 - 15
7y = 4
y = 4/7...so when x = 3, y = 4/7.....(3,4/7)

Annie puts $10 into a vacation jar each week. how much will she have saved by the end of the year?
schepotkina [342]
Solutions 

Annie puts $10 into a vacation jar each week and we need to find out <span>how much will she have saved by the end of the year. To solve the problem first we have to find out how many days there are in a year and convert them into weeks.  

Days in a year = 365

To find weeks divide by 7 since a week consists of 7 days.  

365 </span>÷ 7 = 52
<span>
1 year has 52 weeks 

our next step is to multiply 52 by 10. 

52 x 10 = 520 

By the end of the year she would have saved 520 dollars. </span><span />
