Notice that both equation has a 2f term in them
solve for 2f for both eqs.
2f= 736-6n
2f= 920-10n
since they both equal to 2f, yo can set them equal to each other
736-6n = 920-10n
and solve for n if you want
Let:
Larger number = x
Smaller number = y
-------------------------------------------------------------------------------------------------------------------
x + y = 49
x - y = 21
-------------------------------------------------------------------------------------------------------------------
Isolate the x in the first equation. Subtract y from both sides
x + y (-y) = 49 (-y)
x = 49 - y
-------------------------------------------------------------------------------------------------------------------
Now that we know what x is, plug in 49 - y (which = x) into x in the other equation.
x - y = 21
(49 - y) -y = 21
Simplify.
49 -2y = 21
Note the equal sign. What you do to one side, you do to the other. Do the opposite of PEMDAS. First subtract 49 from both sides
-2y +49 (-49) = 21 (-49)
-2y = 21 - 49
-2y = -28
Next, divide -2 from both sides to isolate the y
-2y/-2 = -28/-2
y = -28/-2
y = 14
-------------------------------------------------------------------------------------------------------------------
Now that we know what y is, plug into one of the equations.
x + y = 49
x + (14) = 49
Isolate the x. Subtract 14 from both sides
x + 14 (-14) = 49 (-14)
x = 49 (-14)
Simplify
x = 35
-------------------------------------------------------------------------------------------------------------------
Answer:
Larger number: 35
Smaller number: 14

Step-by-step explanation:
☆Remember: 
☆Slope-intercept: 
---
☆We need to find the slope first. So just plug in according to the slope formula!

---
☆Now we need to find the y-intercept. We are going to plug in the slope and a set of coordinates to find the y-intercept.

---
☆Now all we need to do is plug in and we are done!
