Multiply the first equation by -2 to eliminate a variable so it becomes:
-12x+8y=48
4x-8y=-32
Add them together.
-8x=16
x=-2
Plug it in one equation.
6(2)-4y=-24
12-4y=-24
-4y=-12
y=3
Ordered pair is: (-2,3)
It wouldnt be an even number but i got 7.3
Answer:
q = ± 
Step-by-step explanation:
We are to solve for q in:
16pq² = 25
q² = 
= ±
= ± 
p - 0.27p = $ 219
0.73p = $ 219
p = $ 219 / 0.73
p = $ 300. i don't know if this is fully right tho
