Question

Find the soln. Of the equation x-4y-14=0 and 5x-y-13 =0

Answer 1

Step-by-step explanation:

..........PLEASE MARK AS BRAINLIEST.........

x-4y=14.........(i)

5x-y=13.........(ii)

Multiplying equation (i) by 5

5(x-4y=14)

5x-20y=70

________________

SUBTRACTING (i) and (ii)

5x-20y=70

-(5x -y= 13)

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

-19y=57

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

y= -3

________________

Substituting value of y in eq. (i)

x-4(-3)=14

x+12=14

x=2

________________

x=2

y=-3
