Answer:
X=5, Y=0
Step-by-step explanation:
-9Y +4X -20=0
-7Y+16X-80=0
1. We can multiply the first equation by 4. This will equal to -36Y +16X-80=0.
-36Y +16X -80 =0
-7Y+16X-80=0
2. We can subtract these two equations.
-36Y +16X -80 =0
-7Y+16X-80=0
We will get -29Y =0. Y=0.
3. Then we can substitute y into the first equation. -9(0) +4x-20 =0. 4x=20. x=5
X=5, Y=0
Answer:
esto literalmente no significa nada jajaja
y un poco sé la respuesta, pero no quiero decírtelo y jeje
Step-by-step explanation:
x = 5.43 + .83m
5.43 + .83 * 5 = 5.43 + 4.15 = $9.58
Keep in mind that, when the logarithm base is not explicitly written, base 10 is assumed, therefore,
