Question

how to find value of x and y if x+y=1/4 and x-y=1/9. pls answer asap with method​

Answer 1

Answer:

Step-by-step explanation:

X+y=1/4 _(1), x-y=1/9. _(2)

x=1/4-y

Now,putting value of x in eq(2).

x-y=1/9

(1/4-y)-y=1/9

-y-y=1/9-1/4

-2y=4-9/36

-2y=-5/36

Y=5/72

Now, putting value of y in eq(1)

x=1/4-y

x=1/4-5/72

x=18-5/72

x=13/72
