Question

The sum of two numbers is 170 and their difference is 26. Find the two numbers. Write the solution as an ordered pair.

Answer 1

x + y = 170
x - y = 26
=======
2x = 196

x = 196/2
x = 98

Put the value of x in any equation
98 + y = 170
y = 170 - 98
y = 72

The two numbers are 98 and 72
Ordered pair: (98 , 72)

Answer 2

x + y = 170----(1)
x - y = 26-----(2)

Add equation 1 and 2
2x = 196
x = 196/2
x = 98

put x in equation (1)
x + y = 170
98+y=170
y = 72

(x,y) =(98 , 72)

Answer 3

Thank you both of you I have many question im not that good at math, are you ready for another question??:D

Answer 4

,To skate at Roller Heaven, each person must pay a membership fee (m) and a fee for each session (f). Art attended five sessions and paid $25 in all. Later, when he had attended 10 sessions, he paid $40 in all. How much is the membership fee and how much are the sessions.
Write a system of two equations with the variables m and f in each to represent this problem.

Answer 5

Yeah sure why not :) Make different threads for different questions :) Thanks :)

Answer 6

In the first part
m+5f=25

And for the second
10f=40
f=40/10
f=4

Put f=4 into the 1st part, that is
m+5f=25
m+5*4=25
m+20=25
m=5

So, sessions fee is 4 and membership fee is 5.

I hope I'm clear :)

Answer 7

thank you, you are really good at math!

Answer 8

Your welcome :)
And thanks :D
