Answer:

To solve the system of equations by elimination, we need another equation that also includes the variables x and y.

Let's say we have the second equation as follows:

2x + 3y = 5

Now we will use the elimination method:

Multiply the first equation by 3 and the second equation by 2 to make the coefficients of x in both equations opposite of each other.

3(3x - 2y) = 3*3

2(2x + 3y) = 2*5

9x - 6y = 9

4x + 6y = 10

Now, add the two equations together:

(9x - 6y) + (4x + 6y) = 9 + 10

9x - 6y + 4x + 6y = 19

(9x + 4x) + (-6y + 6y) = 19

13x + 0y = 19

13x = 19

Divide both sides of the equation by 13:

13x/13 = 19/13

x = 19/13

Now, substitute this value of x into any of the original equations to find the value of y.

Let's use the first equation:

3x - 2y = 3

3(19/13) - 2y = 3

(57/13) - 2y = 3

Now, rearrange the equation to solve for y:

-2y = 3 - 57/13

-2y = 39/13 - 57/13

-2y = -18/13

Divide both sides of the equation by -2:

(-2y)/-2 = (-18/13)/-2

y = 18/13

Therefore, the solution to the system of equations is:

x = 19/13 and y = 18/13.
