Question

the sum of 16 and the difference of 14

Answer 1

a+b=16

a-b=14. (add both equations)

------------

2a=30

a=15

a value substitute in a+b=16

15+b=16

b=16-15=1

Answer 2

As

a+b =16. and

a-b=14

》 a= 14+b

Putting value of 'a' in equation

a+b=16

we get

14+b+b= 16

14+2b=16

2b =16-14

b=2/2

b=1

Hence,

a+b=16

a+1=16

a=16-1

a =15
