Answer:
the oldest is Ty and his age is 24
Step-by-step explanation:
Let us assume the billy age be x
Noah age be y
And, Ty age be z
Now according to the question
y + x = 25 ..........(1)
y + z = 20..........(2)
x + z = 31..............(3)
z = 31 - x
since
y + z = 20
y + 31 - x = 20
y - x = -11 .............(4)
Now solve (1) and (4) equation
So,
y + x = 25
y - x = -11
2y = 36
y = 18
x = 25 - 18
= 7
z = 31-7
= 24
Hence, the oldest is Ty and his age is 24
Answer: y = x
Step-by-step explanation: Since the input for the first equation is 2, the x is 2. Use this for the other equation. Now, your ordered pairs are (2,2) and (1,1). If you find Δy/Δx, you get m = 1. Plug in m to the equation. Next, put any ordered pair in there. For example: 1 = 1(1) + b. If you solve for be the answer is..... 0. Nice. Your final equation is y = 1x + 0, or y = x.
