Question

4x-3y=1 &5x-7y=-2 elimination method​

Answer 1

Step-by-step explanation:

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

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

(1)×5=>20x-15y=5

(2)×4=>20x-28y= -8

(-) (+) (+)

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

13y= 13

=>y=13/13

=>y=1

putting the value of y in equation (1) we get

4x-3y=1

=>4x-3×1=1

=>4x-3=1

=>4x=1+3

=>4x=4

=>x=4/4

=>x=1

so x=1 y=1
