(c)*(d)=8*30+8*4=8*34,=>
c=8
d=34
a+b>a-b, =>a+b=d, a-b=c; =>
{a+b=34
{a-b=8, =>a=b+8 ;
(b+8)+b=34
2b=34-8
b=13
a=13+8=21
Answer: a=21; b=13; c=8; d=34.

2,11
Step-by-step explanation:
y=3×+5 3×2=6+5=11
Using it's formula, it is found that their monthly payments for the mortgage loan will be of $515.45.
<h3>What is the monthly payment formula?</h3>
It is given by:

In which:
- n is the number of payments.
In this problem, we have that the parameters are given as follows:
P = 80000, r = 0.06, n = 25 x 12 = 300.
Hence:
r/12 = 0.06/12 = 0.005.
Then, the monthly payment will be of:
