Question

X-4Y=14
5X-Y=13
Linear equations in to variable

Answer 1

Step-by-step explanation:

X-4Y=14. .....(1)

5X-Y=13 .....(2)

From equation (1)

X= 14+4Y ........(3)

Putting the value of X in Equation (2)

5X-Y=13

5(14+4Y)-Y=13

70+20Y-Y=13

19Y=-57

Y=-57/19

Y=-3

Now putting the value of Y in equation (3)

X=14-4*3

X=14-12

X=2

THEREFORE , the value of X is 2 and the value of Y is -3

Answer 2

Step-by-step explanation:

5x-20y =70

5x - y =13

- - -

-19y =57

y =-57/19 =-3

put -3in equation 1

x+12 =14

x=2

are the values of x and y
