Answer 2

Answer:

$\huge{\boxed{\rm{\red{x=1,y=1}}}}$

Step-by-step explanation:

Given equations are :

4x-3y=1 ----------(1)

5x-7y=-2 --------(2)

now multiply eqn.(1) with 5 and multiply eqn(2) with 4 then subtracting them

20x-15y=5

20x-28y=-8

(-)

--------------------

0+13y=13

--------------------

=>13y=13

=>y=13/13

=>y=1

now from (1)

=>4x-3(1)=1

=>4x-3=1

=>4x=1+3

=>4x=4

=>x=4/4

=>x=1

Therefore x=1 ,y=1

Solution is (1,1)
