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
