Answer:
x and y can both equal 1
Step-by-step explanation:
Since we have:
And we know that they equal each other, 1 should be the best answer.

1 = 1
Answer:
Infinitely many
Step-by-step explanation:
If we multiply the equation x-3y=7 by 3, we get 3x-9y=21, which is also the second equation. That means the two lines are on top of each other, meaning infinite many solutions.
The answer is 5.
the numbers are 5 & -2
Answer:
the amount of interest is $100.80
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 6.3%/100 = 0.063 per year,
then, solving our equation
I = 400 × 0.063 × 4 = 100.8
I = $ 100.80
The simple interest accumulated
on a principal of $ 400.00
at a rate of 6.3% per year
for 4 years is $ 100.80.
