Step-by-step explanation:
X+ 2y=5
X=5-2y
2x+4y=3
2(5-2y)+4y=3
10-4y+4y=3
10=3
5x+2y=3
5(5-2y) +2y=3
25-10y+2y=3
-8y=-22
Y=-22/-8
Y=2.75
6x+12y=30
6(5-2y)+12y=30
30-12y+12y=30
30=30
3x+4y=8
3(5-2y)+4y=8
15-6y+4y=8
-2y=8-15
-2y=-7
Y= -7/-2
Y= 3.5
The question is incomplete. Here is the complete question:
Denise earns $30 an hour. She wants to purchase a computer that costs $2000. Create and solve an inequality to determine the least amount of hours she must work in order to be able to purchase the computer.
Answer:

Denise has to work at least 67 hours in order to buy a computer that costs $2000.
