5x - 2y = 3
-5x + 4y = 9
_________
2y =12
2y/2= 12/2
y = 6

5x - 2(6) = 3
5x -12 = 3
5x -12+12 = 3+12
5x = 15
5x/5 = 15/5
x = 3

Check
-5(3) + 4(6) = 9
-15+24=9
9=9

Tom is the deli manager at a grocery store.He needs to schedule employees to staff the deli department at least 260 person-hours
Drupady [299]
I hope this is right but:
Let n=number of full time employees

260<=20+n*40
260-20<=N*40
240<=n*40
n>=240/40
n>=6 full time employees

which means he would have to hire at least 6 or more fully time employees

Though I'm not sure if the attached file is the graph you are looking for
