Answer:
(x,y) = (2,3)
Step-by-step explanation:
y=5x-7                  (i)
-3x-2y= -12          
-(3x+2y)= -12
3x+2y= 12            (ii)
By putting the value of y from (i) in (ii)
3x+2(5x-7)=12
3x+10x-14=12
13x=12+14
13x= 26
x = 
x= 2
By putting the value of x in (i)
y= 5(2)-7
y= 10-7
y= 3
(x,y) = (2,3)
