Judging by the problem you want me to use substitute method
Since why equals 1/2x-1 you
Do 2(1/2x-1)= x-2
You multiple by 2 cause there’s two on the top for y. So the problem is now 4x-x-2
Combine like terms 3x+2=14
Subtract two on both sides
3x=12
X=4
Go back to the bottom since u know x now do y= 4.1/2-1 solve to get one
Y=1 so your answer is (4,1)

Step-by-step explanation:
Answer:
They meet in 2.22 hours.
Step-by-step explanation:
We can find the time at which Reagan and Nathan meet by equaling the time as follows:
(1)
(2)
Where R is for Reagan and N for Nathan.
Knowing that:
By adding equations (1) and (2) we have:
Therefore, they meet in 2.22 hours.
I hope it helps you!
The molar mass of N2O5 (Dinitrogen pentoxide) is 108.01 g/mol.
X=-4
X-2=2x+2
Subtract 2 and x from both sides to get
-4=1x
