Hello,

Hope you're doing well.

Let equation 2x + 3y = 8 -(1)

And equation -3x + 2y = -1 -(2)

Now multiplying the equation (1) by 3 and equation (2) by 2.

On multiplying we get,

6x + 9y = 24

-6x + 4y = -2

Now adding the equations. On adding we get,

13y=22 so y =22/13

Now putting the value of y in equation (1)

We get the value of x: 2x +3(22/13) = 8

2x = 8- 66/13

2x= 38/13

X = 19/13
