Answer:
ANSWER IS x = -2 and y = -1
Step-by-step explanation:
ANSWER
3x-5y+1=0 ---------(1)
⠀
2x-y+3=0 ----------(2)
multiplying eqn (2) by 5 we get
⠀
10x-5y+15=0 ---------(3)
subtracting eqn (3) from eqn (1) , we get
⠀
(3x-5y+1) - (10x-5y+15) =0-0
⠀
3x-5y+1-10x+5y-15=0
-7x-14=0
⠀
-7x=14
⠀
x = -2
putting the value of x = -2 in eqn (2) we get
2 (-2)-y+3=0
⠀
-4-y+3 =0
⠀
-y-1=0
⠀
-y=1
⠀
y = -1
x = -2 and y = -1
