Question

x+y=10andx-y=4 e kelginvu galnnu naksha vidaan dinda bidisi​

Answer 1

Answer:

value of x = 7 and y = 3

       

Step-by-step explanation:

GIVEN:

x-y=4

and

x+y=10

TO FIND:

vale of x and y

SOLUTION:

x-y=4        ......1

x+y=10      ......2

x=4+y        ......3

putting eq3 in eq2 we get;

∵ x+y=10

(4+y)+y=10

4+2y=10

2y=10-4

2y=6

y=$\frac{6}{2}$

y=3

as we got the vale of y ,

now put vale in eq1

∴ x-y=4

x-3=4

x=7

value of x=3 and y=7
