Answer:
(6,6)
Step-by-step explanation:
3x+5y=48
-3x+5y=12
Ok so when you're doing elimination you want to combine all of the like terms. In this case, we need to combine 3x and -3x, 5y and 5y, and 48 and 12. 3x and -3x cancel out, so that leaves you with 10y=60. Solving for y gives you y=6. Now you need to solve for x, so using 3x+5y=48, by plugging in y you get 3x+(5*6)=48. Simplifying that gives you 3x+30=48. Subtract 30 and divide by 3, and you get x=6. Thus the Answer is (x,y) or (6,6)
Answer:
6 months
Step-by-step explanation:
27 + 8x = 75
x = months which is what you're trying to figure out
1. subtract 27 from 27 and 75
2. then you have 8x = 48
3. divide both sides by 8 so x=6
4. 6 months
x - hip-hop CDs
x+3 - rock CDs
6 hip-hop CDs, 9 rock CDs
Answer: p = -17
