Answer 2

Answer:y=1 and x=-1

Step-by-step explanation:

2x-y+3=0   (1) equation

3x-7y+10=0  (2) equation

now multiply 1 equation by 3 and 2 equation by 2 we get

6x-3y+9=0

6x-14y+20=0

now we subtract so answer is

11y=11

y=1

and now put the value of y in 1 equation we get

2x-1-3

2x+2

x=-2
