Answer:

The system of equations is (x, y) = (13, 12).

Explanation:

To evaluate the system of equations:

3x - 2y = 15

7x - 3y = 15

We can use either the substitution or elimination method to solve the system.

Using substitution method:

From the first equation, we can isolate x as follows:

3x - 2y = 15

3x = 2y + 15

x = (2/3)y + 5

Substitute this expression for x into the second equation:

7x - 3y = 15

7[(2/3)y + 5] - 3y = 15

Simplify and solve for y:

(14/3)y + 35 - 3y = 15

(-5/3)y = -20

y = 12

Now that we know y = 12, we can use either equation to solve for x:

3x - 2y = 15

3x - 2(12) = 15

3x - 24 = 15

3x = 39

x = 13

Therefore, the solution to the system of equations is (x, y) = (13, 12).
