Answer:
or 
Step-by-step explanation:
Given:
We are to find the values of 
such that these two functions are equal.
Substitute 
.
We get 
Hence for we have the functions to be equal.
Now for 
We see the functions are once again equal.
Answer:
The product of these two numbers is 1239.
Step-by-step explanation:
Given that
a + b = 80
a - b = 38
Add both equation :
a + b = 80
a - b = 38
2a = 118
a = 59
Put value of a in any 1st equation
a + b = 80
b = 80 - 59
b = 21
<em>Product : </em>
a x b = 59 x 21
= 1239
