Sagot :
Answer:
a = 5
b = 16
Step-by-step explanation:
Solving the Problem
We're told that
- plugging in the coordinates of (2,3) into the equation 7x - 3y will find the value of a
- plugging in the coordinates of (a, a+1) into the equation 2x + y will find the value of b
and we need to find the values of a and b.

We can start by finding the value of a from the given equation and values.
7(2) - 3(3) = 14 - 9 = 5 = a
This means that (a, a + 1) = (5, 6).
So, we can plug the coordinates into its equation to find the value of b.
2(5) + 6 = 10 + 6 = 16 = b
