Answer 1

Step-by-step explanation:

3x-7y+10=0.....(1)

y-2x-3=0..........(2)

from (2)

y=3+2x.........(3)

using (3) in (1)

3x-7(3+2x)+10=0

3x-21-14x+10=0

3x-14x+10-21=0

11x-11=0

11x=11

x=11/11

x=1

using this value in (3)

we get,

y=3+2(1)

y=3+2

y=5

hence, x=1 and y=5 are the required solution
