-3 • (5x + 2y = 7)
-15x - 6y = -21
-2x + 6y = 9
__________
-17x = -12
x = 12/17
5(12/17) + 2y = 7
2y = 7 - 60/17
2y = 3.47
y = 1.735
The best and most correct answer among the choices provided by the question is the third choice.
The notation "<span>AB (with line over) =4" is the equation that has the most correct notation.</span>
I hope my answer has come to your help. God bless and have a nice day ahead!
Answer: 200
Step-by-step explanation:
since 10 is one part
10 x 20 = 200
You would solve this with simultaneous equations, so if we write it as:
5n + 2p = 9
3n + 2p = 6
(subtract)
2n = 3
÷ 2
notebooks = 1.5
Now you would substitute it in:
(3 × 1.5) + 2p = 6
4.5 + 2p = 6
- 4.5
2p = 1.5
÷ 2
pens = 0.75
So your final answer is notebooks are $1.50 and pens are $0.75, I hope this helps!
