X-4Y=145X-Y=13Linear equations in to variable

Answer»

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
