Given
a + b =10
b+ c = 15
By subtracting them, we get
a - c = - 5
c+a =13 (given)
By again subtracting
We have - 2c =-18
c=18
Putting the value of 'c' in c+a =13
a = 4
a + b =10
b+ c = 15
By subtracting them, we get
a - c = - 5
c+a =13 (given)
By again subtracting
We have - 2c =-18
c=18
Putting the value of 'c' in c+a =13
