Answer:
8x + 3y = 5
3x - 2y = 5
multiplying upper equation by 2 and lower by 3 to make y variables contant
(8x + 3y = 5)*2
(3x - 2y = 5)*3
16x + 6y = 10
9x - 6y = 15
--------------------
25x + 0 = 25
so, x = 25/25
x = 1
now put the value of x in equation 1
8x + 3y = 5
8*1 + 3y = 5
3y = 5 - 8
y = -3/3
y = -1
therefor x=1 and y=-1
