4.25-1.75= 2.5
2.5/25= 0.1
The final answer is 0.1
the equation is 2x-1 right so all you have to do is plug and go
2x-1
2x10-1
20-1
19
so your answer would be A)19

2 You have that:

3. Then, you can substitute it into the other equation and solve for x:

4. Now you can obtain y:


5. The answer is:
(4,3)
