How would I translate and solve the following word problem into a pair of linear equations in two variables?
The sum of two numbers is 52, and their difference is 6.
What are the numbers?
x = one number
y = the other number
x+y = sum of the two numbers
(just put a + between them to get their sum)
x-y = difference of the two numbers
(just put a minus between them to get
their difference)
Translate this part of the first sentence:
>>..The sum of two numbers is 52..<<
x+y = 52
Now translate this part:
>>..their difference is 6..<<
x-y = 6
So you have the system of equations:
Can you solve that? If not post again asking how.
Answer: x=29, y=23
