Answer:
5 percent per annum
Step-by-step explanation:
interest rate:
interest: $1800
principal: $18000
duration: 2 years
1800/ 18000 * 100
result is 10%
Since interest is 10% in 2 years, 10% / 2
interest is 5% per year.

Answer:
y = -6/7
x = 6/49
Step-by-step explanation:
-7x -y = 0
7x +8y = -6
Add the two equations together to eliminate x
-7x -y = 0
7x +8y = -6
-----------------------
7y = -6
Divide by 7
7y/7 = -6/7
y = -6/7
Now we need to find x
-7x -y = 0
-7x -(-6/7) =0
-7x +(6/7) =0
-7x +6/7 -6/7 =0-6/7
-7x = -6/7
Divide each side by -7
-7x/-7 = -6/7 *-1/7
x = 6/49
