Solution

To solve the system of equations, we can use either substitution or elimination method. Here, I'll use the elimination method.

The system of equations is:

2x + 3y = 7 ...(1)

3x - 5y = 1 ...(2)

First, we'll make the coefficients of y the same in both equations. To do this, multiply equation (1) by 5 and equation (2) by 3:

10x + 15y = 35 ...(3)

9x - 15y = 3 ...(4)

Now, add equation (3) and equation (4) together:

(10x + 9x) = 35 + 3

19x = 38

Divide both sides by 19 to solve for x:

x = 38 / 19

x = 2

Substitute x = 2 into equation (1):

2*2 + 3y = 7

4 + 3y = 7

3y = 7 - 4

3y = 3

Divide both sides by 3 to solve for y:

y = 3 / 3

y = 1

So, the solution to the system of equations is x = 2 and y = 1. Therefore, the answer is option a. (2, 1).
